Hi, Boki:

 

Yes, it may be helpful and easier to have a helper property FirstChild. Thank you.

 

Here are some settings I could not find in NG6, from NG5 Grid,AppearanceOptions, Grid.Options:

 

*ao3DGridLines = ?
*aoAlphaBlendedSelection = ActiveView.SelectionStyle := stAlphaBlended;
*aoBoldTextSelection = ?
*aoIndicateSelectedCell = ?

 

Can you confirm my guesses?

 

*goGrid = ActiveView.GridLines?

*goHeader = ActiveView.ShowHeader?
*goIndicator = ActiveView.ShowIndicator?
*goFooter = ActiveView.ShowFooter?
*goMultiSelect = ?
*goRowResizing = ActiveView.RowResizing := True;
*goRowMoving = ActiveView.RowMoving := True;
*goSelectFullRow = ?

 

BTW, what is ActiveView.ShowInsertRow mean/do?

 

Thank you, again. I am getting closer to being done. 

Chuck

Grid.GridSpace

 

Hi, Boki:

Here is some code I have been using with an undocumented property in NextGrid5. How do I get the same information now?

 

FOR i := 0 TO MainForm.gridSelectNMTPaths.Columns.Count - 1 DO
  BEGIN
    IF MainForm.gridSelectNMTPaths.Columns[i].Visible THEN
    BEGIN
      ScanColWidth := ScanColWidth + MainForm.gridSelectNMTPaths.
        Columns[i].Width;
      GridLinesWidth := GridLinesWidth +
      // need the cast, since the prop conflicts with TLabelPosition
      // GridSpace is not documented, but is the space in pixels for the
      // grid lines used in the grid: lpLeft, lpRight, lpBottom, lpTop
        MainForm.gridSelectNMTPaths.GridSpace[TGridLinePosition(lpLeft)] +
        MainForm.gridSelectNMTPaths.GridSpace[TGridLinePosition(lpRight)];
    END;
 
Thank you!
Chuck

TNxMemoInplaceEdit, TNxToolSeparator, TNxSpinButtonSet = Cannot find these in NG6

 

Grid.ReadOnly = ? NG6

Grid.VisibleRows = ? NG6

 

Thank you, Boki! I am real close now.

FYI:

NxNumberColumn.Increment for NxNumberColumn6 is "Incrememnt" I am guessing a misspelling.

Hi, Boki:

 

How do you use Columns.OnSetCell to replace Grid.OnCellFormating for changing the Font properties which are not equally available to all columns?

 

for instance I am currently (NG5) doing this in the generic routine called by the OnCellFormating event:

 

IF (SelectedRow = aRow) AND (SelectedCol = ACol) then
      // this works with SelectFullRow option
      BEGIN
        TextColor := clBlack;
        FontStyle := [fsBold];
      END
    end
    else
    begin
//otherwise keep the current color/style scheme
      TextColor := Columns[ACol].Font.Color;
      FontStyle := Columns[ACol].Font.Style;
    end;
 
Thank you,
Chuck

Hi,

Sorry for delay,

If you want you can access Cell's properties such as Font.

Or, inside OnSetCell event you can set Column's properties. For example Column.Font . This event is called just a moment before cell is painted so you can configure column before cell is being drawn.

But beside this options, I'm thinking about having back OnFormatCell (or similar).

Thanks, Boki:

 

When I tried in one of your NG6 Demos to use OnSetCell the Cell parameter does not have Font exposed for use.

The NextGrid61.Columns[ACol].Font is available.

It would be nice to have a Grid wide event, such as OnFormatCell that applies to all cells, otherwise we have to add that event to every column.

 

I made a mistake in how I called  NextGrid61.Columns[ACol].Font before and thus did not see Font available. I used  Columns(), not [ ].

 

Regarding my other posts:

I figured out the Grid options and confirmed them on my own.

The ApperanceOptions I am guessing are really not necessary any more. The 3dGridLines is probably only good with Aero which no longer exists in Win10.

The two *aoBoldTextSelection = ?

*aoIndicateSelectedCell = ?

Might be useful. What I am noticing is that grid and cells looks different in NG6, but it would be nice to be able to highlight all selected cells in some way.

 

Did you see?: FYI:

NxNumberColumn.Increment for NxNumberColumn6 is "Incrememnt" I am guessing a misspelling.

 

Grid.ReadOnly = ? NG6

Grid.VisibleRows = ? NG6

 

TNxMemoInplaceEdit, TNxToolSeparator, TNxSpinButtonSet = Cannot find these in NG6 What would be their functional replacements?

 

Do you have an equivalent property: GridSpace?

MainForm.gridSelectNMTPaths.GridSpace[TGridLinePosition(lpLeft)] +

        MainForm.gridSelectNMTPaths.GridSpace[TGridLinePosition(lpRight)];
 
BTW, what is ActiveView.ShowInsertRow mean/do?
 
The NG6 equivalent for:
OnHeaderDblClick = ?

OnCellHint = ?
OnChange = ?

 

I have more, but will post them separately. I going through each form's PAS and DFM making changes. 

 

Here's another: OnVerticalScroll in NG6 has the single param, Sender, while in NG5 has Position. That Position param is very handy. I have been using the code below to keep users from over scrolling in the grid:

 WITH Grid DO
  BEGIN
    // if using scroll bar, it can go past the last row index causing a list
    // index out of bounds
    IF (Position > RowCount - 1) OR (Position < 0) THEN
    BEGIN
          exit;
    END;
    Repaint; // needed for XE2 paint problems
  END;

 

And another:

We have RowExists, but not ColumnExists. NG5 was Columns[].Exists, now nothing. Definitely need this! or its equivalent.

 

Thank you!

Chuck

Hi,

Yes, you set column properties just before cell is being drawn. Only thing to remember is to return them back for next cell. For example if you set red font. But I agree that OnCellFormating would be better. I will add it in upcoming release.

I also added ReadOnly property for Grid.

Inside Column now you have more events (also OnHeaderClick and similar).

InvertSelection property is maybe what you need for Full row selection?

I will see what else we miss. I think most of them are easy to add.

Hi, Boki:

 

Consider this post a summary of what events, properties and methods that I will need to be included in NextGrid6 or their functional equivalents so that I can compile my application as I move from using NextGrid5. My intent here is to make it easier for others following this series of posts, too.

 

Events: 

Below events are only the ones that I use and if a ? indicate that I need the NG6 replacement

 

OnHeaderDblClick = ?
OnCellHint = ?
OnChange = ?

OnApplyEditText = ?

OnEdit = ?
OnCustomDrawHeader = Col.OnDrawContent, OnDrawBackground? Boki, does either of these two replace the event?
OnHeaderClick = Column.OnHeaderClick? Col.OnHeaderButtonClick? Boki, which is the best replacement?
OnSelectCell = OnSelect
OnCellColoring = ActiveView.OnGetCellColor (different State param)
NxReportGridView61GetCellColor(Sender: TObject; ACol,  ARow: Integer; var CellColor: TColor; State: TNxCellPaintingState);

  TNxCellPaintingState = set of (csSelected, csFocused, csEmpty, csPressed)

OnEditText = ?
OnCellFormating = Columns.OnSetCell procedure TForm1.NxTreeColumn61SetCell(Sender: TObject; ACol, ARow: Integer;  Cell: INxBaseCell); THE PROBLEM IS THAT CELL does not have Font settings! Need to reference the Columns(ACol).Font Boki said he would replace the OnCellFormting event.
OnExpand = OnRowExpandedChange
OnColumnResize = Column.OnResize? Boki, is this the replacement?

OnBeforeEdit = OnBeforeEdit with the addition in NG6 of the param, Text.

OnBeforeSelect = OnBeforeSelect with the addition in NG6 of the params Key and Shift.

OnCellClick = OnCellClick with the addition of Button (mouse button)

OnVertical/HorizontalScroll = OnVertical/HorizontalScroll in NG6, but the param POSITION is missing. I use this param and need a replacement 

 

 

Property Settings:

TAppearanceOptions: as far as I can tell none of these exist in NG6; not sure they even apply to the newer looking grid. I have removed reference to these options in my application until what is available is more clear.

 

* = denotes the AO's that I actually use in NG5

 

*ao3DGridLines = ?

*aoAlphaBlendedSelection = ?
*aoBoldTextSelection = ?
aoDontFillCells = ?
aoHideFocus = ?
aoHideSelection = ?
aoHighlightSlideCells = ?
aoHintMarks = ?
*aoIndicateSelectedCell = ?
aoIndicateSortedColumn = ?

 

TGridOptions: for these options, all the ones that I use in NG5 are available in NG6. For my application to compile right now I do not need any of the missing options.

 

goArrowKeyExitEditing = ?

goCanHideColumn = ?,

goDisableColumnMoving =  ActiveView.ColumnMoving = false

goDisableKeys = ?

goEscClearEdit = ?

goFooter = ActiveView.ShowFooter 

goGrid = ActiveView.GridLines

goHeader = ActiveView.ShowHeader 

goIndicator = ActiveView.ShowIndicator 

goInput = ?

goLockFixedCols = ?

goMultiSelect = Grid.MultiSelect := Boolean;

goRowResizing = ActiveView.RowResizing

goRowMoving = ActiveView.RowMoving

goSecondClickEdit = ?

goSelectFullRow = Grid.SelectFullRow := Boolean;

goUseDefaultValues = ?

goInplaceEditEvents = ?

 

other options:

 

HeaderSize = ActiveView.HeaderHeight

RowSize = RowHeight

SelectionMoveDirection: no longer

HeaderStyle = hsVista,, hsAuto  DO NOT USE any longer

InnerWidth = ?

GridSpace = ?, Undocumented property in NG5, but something I use to find the exact size of a grid.

ReadOnly = ?

VisibleRows = ?

SelectedColumn = SelectedCol

 

Column.Options:  Now are set via property settings rather than via the set

ShowTextFitHint := boolean

MultiLine := boolean

Editing := boolean

EditorAutoSelect = AutoEditing Is this same Boki?

DefaultWidth = use Width instead

DefaultValue = in NumberCols is a number, not a text number in DFM

Increment in Number Col, does not exist it is now “Incrememnt” MISSPELLING 

ShowLines = True; for NxTreeColumn; this is not a publised property, but available as a property to set.

Progress.RoundedCorners: NO LONGER

 

Header options:

Header.Orientation = hoHorizontal, hoVertical now: orHorizontal, orVertical

 

WrapKind: this property is only in some columns which makes doing a generic Columns[x].Wrapkind := wkWordWrap impossible without knowing the column class in advance. Boki, can you fix this?

 

coEditing = Columns[x].Editing := Boolean
coCanClick = ?
coCanInput = ?
coPublicUsing = NA
coShowTextFitHint = Col.ShowTextFitHint = true
coCanSort = Col.Sorted ?
coEditorAutoSelect = Column.AutoEditing := Boolean
coAutoSize = Column.AutoSize = boolean
coSearchColumn = ?
coImageForIcon = ?
coFixedSize = col.FixedWidth
coDontHighlight = (number col)
Editor = InPlaceEdit ? Noticed that a CheckBox Column cannot use a nxCheckBox editor, why is that?

 

Methods:

Cell[].Clear =?
ApplyEditing =?
GetRowAtPos =?
GetColumnAtPos =?
GetColumnAtPos.VisibleIndex =?
IsTextFit =?
GetCellRect =?
GetCellTop =?
GetChildCount =?
GetParent = ?

FirstChild = Row(x).ChildRow(0), would be helpful to have FirstChild

RefreshRange =?

NoSelection (deselects rows) =?
RefreshColumn =?

SelectLastRow =?

MoveSelectionDown =?
MoveSelectionUp =?

GetNextSibling, GetPrevSibling = Row(SelectedRow).NextSibling;

FirstRow = TNxReportGridView6(ActiveView).FirstIndex or NxReportGridView61.FirstIndex

Expanded() = Row().Expanded

ScrollToRow() = ActiveView.ScrollToRow()
GetFirstChild(Arow) = Grid.Row().ChildRow(0) ; FirstChild would be nice
GetLastChild() = ?

Grid.GetLevel = Grid.Row(x).GetLevel

HasChildren(x) = Row(x).HasChildren

Expanded[x] = Row(x).Expanded

 

Miscellaneous:

 

TNxMemoInplaceEdit does not seem to exist in NG6

 

TNxToolBar6 is quite different from the NG5 equivalent:

TNxSeparator is now a property setting of each added Button to the ToolBar, the buttons do not have a OnClick event, rather the ToolBar has a OnButtonClick event with Index as a parameter. It is not clear, but I am assuming the Index refers to the button index. The problem is that that OnButtonClick does not seem to functioning at all.

 

Thank you, Boki for a great upgrade to NG5!

I will continue updating one by one.

OnHeaderClick can be found in ActiveView.OnHeaderMouseDown . There you can also Button (for double click, right, left button) and also Col parameter.

For edit events, you can check this article:
http://developer.ber...=683&lang=en-us

This part of component was long over-due so I changed it a bit.

goInput is ShowInsertRow in GridView.

Update: For moving selection you can use:

  NextGrid61.SelectFirst();
  NextGrid61.SelectLast();
  NextGrid61.MoveByRow();
  NextGrid61.MoveByColumn();
Most of them support TShiftState parameter so you can keep existing selection and move to next.

Hi, Boki:

I had to step away from my app conversion from NextGrid 5 to NextGrid6 and return to work on the current app version because of user requests. Anyway it has been about 4 months. I updated the NG6 source code (Feb 2018) and reviewed the changes in your PDF and note that it looks like all the changes I requested and you said you would do are still not completed. Can you give me a status update, since now I have a lot of pressure to get my app converted.

 

If you review the posts I made you will see I listed pretty much everything that does not seem to have an equivalent in NG6. Without these changes I cannot go forward so would appreciate your response. In your above posted replies you did give me some equivalents which are helpful, but there still are many properties, methods and events which simply do not appear to exist in NG6 and without them I cannot maintain the current functionality of my application.

 

I really cannot go backward to NG5 at this time, because of some serious screen drawing issues with NextGrid5 for users on occasion. Having looked at the NG6, I really like what you have done to modularize the components and their properties, but at this point I really need to be able to have the same functionality as NG5 and go forward with NG6. 

 

At some point I am sure other users would appreciate a NG5 to NG6 conversion map. 

 

Thank you!

Chuck Belanger

Hi Chuck,

Can you tell me which properties/methods you need most urgently. Maybe I can speed up on them, but most of this properties are inside v6.

Thank you, Boki, for your reply and willingness to help my conversion project from NG5 to NG6.

For a list of all properties, methods and events that are missing (or perhaps I cannot find the equivalent in NG6), see my post 13, October, 2017. You did address a few of them in the subsequent replies, which helped but does not address the missing PMEs.

 

There really is no short list of important ones, because all that I list are currently being used in my program and for me to be able to compile the program with NG6 (I am also moving from Delphi XE2 to 10.2, Tokyo), I will need the equivalent functionality.

 

At this point, I need an honest answer, ok? Would it be best for me to go back to using NG5 until such time that NG6 has the equivalent functionality. I have already done a lot of conversion, but I really don't have months to wait on NG6 at this point. I have the original pas/dfm files before the NG6 conversion, so could go backward. This way I can get a program compiled in Delphi 10.2 and I can then come back later to upgrade to NG6. My concerns about NG5 stand, though, i.e. screen redraw issues. Right now I have some hacks in place that reduce that issue to only once in a while.

Thank you!

Chuck

Hi Chuck,

Most of items from your list are done in last several months, but some of them like 3D Grid are not yet. I'm not sure if I can do it quickly and if people like this option (today's trends are flat ui).

Here are some more properties/methods matching:

AppearanceOptions:

aoHideFocus = NextGrid6.HideFocus
aoHintMarks = NextGrid6.AppearanceOptions.aoHintIndicators

aoBoldSelectedText added.

goInput = View.ShowInsertRow

Methods

ApplyEditing = AssignEditing
SelectLastRow = SelectLast
CellRect = View.GetCellRect
GetRowAtPos = View.GetItemAtPos
GetParent = Row[x].ParentRow
GetFirstChild = Row[x].FirstChild
GetColumnAtPos = View.GetColumnAt
GetChildCount = Row[x].ChildRowCount

Cell

- There is now Hint property for Cell.
- Also for Clear there is Revert (reset value of cell to default).

Thank you, Boki, for your quick review and reply.

That 3d grid property is not important in Win10 and is cosmetic only, so I am unconcerned about that particular property setting. I agree look and feel is trending toward FLAT.

The events and methods are the most important. 

Are you saying that you have added all the missing events and methods, because I am getting Delphi errors showing otherwise?

 

Thank you!

Chuck

Hello Chuck,

Please note that I didn't add all from your list, but progressing (you can see that I slowly update your list). Also, not sure if you downloaded latest release since I added some of them recently.

Thank you, Boki.

I downloaded the February update. 

What I will do is go through the Delphi errors (regarding NextGrid) and go over my list to see what is missing so that we can focus on only those PME's that I need to be able to compile my program.

Hi, Boki:

Here's a start of my current list of NG5 PME's needed for converting my application to NG6. Yes, this list is shorter! Thank you!

There are still more compile errors that may or may not indicate more conversion errors. I will be reviewing those and post those as I confirm them.

 

OnApplyEditText = ?
OnEditText = ?
OnCellFormating = Columns.OnSetCell procedure TForm1.NxTreeColumn61SetCell(Sender: TObject; ACol, ARow: Integer;  Cell: INxBaseCell); THE PROBLEM IS THAT CELL does not have Font settings! Need to reference the Columns(ACol).Font, but not every Column has a font property either.

OnColumnResize = Column.OnResize? (please confirm)
OnEdit = ?
OnHeaderClick =?
OnHeaderDblClick =?
OnCellHint =?
OnChange =?
OnCustomDrawHeader =?

 

Increment in Number Col, does not exist it is now “Incrememnt” Spelling error!
Did you catch and change this back to Increment? Because other forms are saying “incrememnt” property does not exist after I changed to misspelled property name. Better to have it spelled correctly. I will be happy to change back to whatever the current spelling.
