Superclass a window

Richard_And_Trisha

I want to setup a tr_Window that has a method Opening() that basically set the toolbar and set the background colour.
instead of calling it everytime in the individual window, I want to setup on original window to use tr_Window instead of Window.

when I compile, I got the following error. what do I need to do ???

[Error] <generated: designer layout for frmMainMenu> Line 7: Property '__ObjoStudioDesignerInitialised' in class 'frmMainMenu' hides a property in a superclass.
[Error] <generated: designer layout for frmMainMenu> Line 14: Method '__ObjoStudioInitialiseDesigner' in class 'frmMainMenu' hides a method in a superclass. Use 'Override' if this is intentional.

You haven’t done anything wrong - this was an Objo Studio bug. Both designer-backed Windows were receiving identically named internal layout helpers, causing the superclass conflicts shown by the compiler.

This is now fixed and will be included in the next release: https://feedback.objo.dev/bug/1322

After updating Studio, tr_Window can remain a Window item and frmMainMenu can use it as its Superclass. Studio will initialise the tr_Window layout first and the frmMainMenu layout second.

A couple of details:

Controls from both layouts will exist at runtime.
Settings in the derived Window’s layout take precedence over settings from the base layout.
Control names must be unique across both Windows.
The derived Window’s Designer displays only its own controls; inherited controls are created at runtime.

Until the next release, the workaround is to make tr_Window a normal Class inheriting Window, as described above.

Garry how to make sure the Opening() in tr_window is run first and then the Opening() in the frmMainMenu is run.

I probably going to put the code like setting the background color or the sidebar color or maybe toolbar inside the tr_Window
