PaintDesignControl Procedure

rbuser

Hello,

I've writen some RB-components with RB 6.02. Now we bought RB 10.05 and I
miss the PaintDesignControl-nethod, which was used in 6.02 to draw the
component in the designer-window.

My components are drawn on the printer and on the screen device, but not in
the designer. I've tried to overwrite the invalidate-method, but I have no
canvas to draw.

What can I do?



Thank you for answer

Hi Christine,

- RB 9 introduced a new RCL architecture, here is an article with details...

---------------------------------------
Article: RB 9 Architecture Changes
---------------------------------------

ReportBuilder 9 includes architecture changes to more cleanly separate
Designer code from Report code. The code related to component popup menus
and design controls has been broken out into separate classes.

For an example, check out RBuilder\Demos\RCL.


The myChkBox.pas unit contains the component classes....


TppCustomComponent

|
|

TMyCustomCheckBox

|
|-- TmyCheckBox
|
|-- TmyDBCheckBox


The myChkBoxDesign.pas unit contains popup menu and design control classes.
These are compiled into a separate package.


A. Popup Menu classes....

TppComponentPopupMenu

|
|

TmyCustomCheckBoxPopupMenu

|
|-- TmyCheckBoxPopupMenu
|
|-- TmyDBCheckBoxPopupMenu


B. Design Control classes.....



TmyCustomCheckBoxControl

|
|

TmyCustomCheckBoxPopupMenu

|
|-- TmyCheckBoxControl
|
|-- TmyDBCheckBoxControl
