Hello Boki,

TNxPagecontrol: i noticed that it is possible to copy one tabsheet on another tabsheet. I think this should make a new tabpage or give an error message. Deleting this copied tabsheet gives in the best way only an access violation, in the worst case it crashes the IDE.

Helmut

[edit]: just found out that if you have one tabsheet copied on aonother one and you run the program it gives unexplainable exceptions which stops the program and you have to use taskmanager to kill it!

Hi Helmut,

Can you please send me a code that you use for copying tabsheets.

Thank you

Hello Boki,

start IDE, take a form, put a pagecontrol on it with two tabsheets, go the first tabsheet, put a button on it (it happens only if you have at least one component on the tabsheet you copy) and then click on the tabsheet so that it is marked and press <Ctrl><C>, change to second tabsheet, click on it and then press <Ctrl><V>, you should see the button copied on the second tabsheet.
Now run the program, it will give you an errormessage when you close it.
Or change to "view form as text", you will get an error message. Trying to go back not possible, you have to close IDE.
And after that if you reopen the project again you will not see this form any more and you get also error messages when trying to close the IDE. The only change is to edit the .pas and .dfm manually and remove this copied tabsheet.

I use windows 7 home and Delphi XE prof.

bye,
Helmut

Hello Helmut,

Hm, this is a tricky situation. I will need to somehow enable having TabSheet outside PageControl, but this will open more situations. I will need to do some testings, then I will have a answer.

Best regards

Hello Boki,

maybe you do it like the standard pagecontrol:
when a tabpage is selected, then <Ctrl><C> and also entry "copy" in the menu is disabled / not working.

Hello Helmut,

I only hope that Borland didn't add a hard-coded support for their PageControl in IDE But, maybe there is a option to control this.

Best regards
