EDIT: ElementaryOS 7 (Ubuntu 22.04 based)
EDIT 2: Appears to be fixed in PB 6.30!
Here's an odd one... Try mouse-resizing the window, which has a callback, which resizes the CanvasGadget, which also has a callback.
If I resize the window diagonally, I get both callbacks to trigger and it redraws correctly.
If I resize the window horizontally-only or vertically-only, it only triggers the window callback, not the gadget callback, and the redraw doesn't happen.
Code: Select all
CompilerIf #PB_Compiler_OS <> #PB_OS_Linux
MessageRequester("Warning", "This bug report is intended for Linux!", #PB_MessageRequester_Warning)
CompilerEndIf
OpenWindow(0, 0, 0, 480, 480, "Resize Callback Test", #PB_Window_ScreenCentered | #PB_Window_SizeGadget)
CanvasGadget(0, 0, 0, WindowWidth(0), WindowHeight(0), #PB_Canvas_Keyboard)
Procedure SizeWindowCallback()
Debug #PB_Compiler_Procedure
ResizeGadget(0, 0, 0, WindowWidth(0), WindowHeight(0))
EndProcedure
Procedure ResizeCanvasCallback()
Debug #PB_Compiler_Procedure
If StartDrawing(CanvasOutput(0))
Box(0, 0, OutputWidth(), OutputHeight(), #White)
LineXY(0, 0, OutputWidth(), OutputHeight(), #Red)
LineXY(OutputWidth(), 0, 0, OutputHeight(), #Red)
StopDrawing()
EndIf
EndProcedure
ResizeCanvasCallback()
ClearDebugOutput()
MessageRequester("Info", "Try resizing window diagonally, horizontally, vertically...", #PB_MessageRequester_Info)
BindEvent(#PB_Event_SizeWindow, @SizeWindowCallback())
BindGadgetEvent(0, @ResizeCanvasCallback(), #PB_EventType_Resize)
;ResizeGadget(0, #PB_Ignore, #PB_Ignore, 490, 480) ; resize width only
;ResizeGadget(0, #PB_Ignore, #PB_Ignore, 480, 490) ; resize height only
;ResizeGadget(0, #PB_Ignore, #PB_Ignore, 490, 490) ; resize width and height - gets callback!
Repeat
Until WaitWindowEvent() = #PB_Event_CloseWindow
If ResizeGadget() only changes one dimension, I don't get the EventType_Resize callback.
If I change both width AND height, I get the callback.
