Two subclassed canvas objects and their pressed events

AndiG

Summary

I made two buttons from Canvas, one is a little switch control, the other a normal button. When I open the Window1 in the solution, I get this view:

Now, when I delete one of this 2 methods, this happens:

Now I can add the Pressed-event to the 2nd Canvas button and everything looks fine. But when I close the tab of Window1 and open it again, everything is like in the upper screenshot.

Thanks for the clear report. I’ve reproduced and fixed this.

The _Pressed method names are internal plumbing that Studio uses to wire event handlers, and they shouldn’t normally appear in the member sidebar. The bug was that, when reopening the window tab, Studio rebuilt the member tree before it had wired up the project-defined events for custom controls. Because of that, handlers like CanvasButton1_Pressed and CanvasSwitch1_Pressed weren’t recognised as control event handlers and leaked into Methods.

The fix makes sure custom control events are available before the sidebar is rebuilt. I’ve also added a regression test with two Canvas subclasses that both declare Pressed, so this case should stay covered.

Fixed in the next release: https://feedback.objo.dev/bug/557
