 Posted: Mon Mar 28, 2005 12:49 pm Post subject: drawing pages with shapes |
 |
|
Hello evetybody,
I need some advise on how to approach to the following:
I have created a simple application basically with a main form with a
scrolling box area inside it (alClient aligned) where the user can drop and
move some simple shapes (rectangles, squares, ellipses) around. The shapes
are all derived fromTGraphicControl and i create them at runtime with the
Scrollbox as Parent.
Now I'd like to add a "page" feature so that the user could draw not only on
the "main form scroll box area" but also be able to add "pages" like the
main one and then save/load all the created pages, each one containing the
shapes dropped there by the user.
How could I do something like this?
Any sample would be greatly appreciated
Thanks in advance for your suggestions/tips

Drop a TPagecontrol on the form, create a tabsheet for each of the pages
(perhaps only one at start if the user can create more at will), drop your
scrollbox on the tabsheet.
You now have as many scrollboxes as you have tabsheets, so you have to make
sure you refer to the correct scrollbox (the one on the active tabsheet) when
handling control drops etc.. If the scrollbox is the only control on a tabsheet
you can get its reference with
scrollbox := Pagecontrol.activepage.Controls[0] as TScrollbox;
Needs a few safeguards, of course, for example checking that ActivePage is <>
nil before you access it.

DtpDocuments has all this functionality, but might be overkill. Nevertheless
I think it could help you to check it out (there's a trial):
http://www.simdesign.nl/dtpdocuments.html
Have a look at the editor demo (comes with sources).
The individual pages are accessible through the thumbnails at the bottom.
Kind regards,
