CanvasGadget and borderless window style

[Dirk Geppert]

On mobile devices (tested with safari, chrome and firefox on iOS14),
the CanvasGadget will not send evnts, if the window style is #PB_Window_BorderLess or #PB_Window_Background

Code: Select all

OpenWindow(0, 0, 0, 320, 320, "Canvas container example", #PB_Window_BorderLess)

ContainerGadget(2, 0, 0, 320, 320)
  CanvasGadget(0, 10, 10, 300, 300, #PB_Canvas_Container)
    ButtonGadget(1, 10, 10, 80, 30, "Clean up")
  CloseGadgetList()
CloseGadgetList()    
  Procedure GadgetEvents()
    
    Select EventGadget() 
      Case 0
        If EventType() = #PB_EventType_LeftButtonDown Or (EventType() = #PB_EventType_MouseMove And GetGadgetAttribute(0, #PB_Canvas_Buttons) & #PB_Canvas_LeftButton)
          If StartDrawing(CanvasOutput(0))
            x = GetGadgetAttribute(0, #PB_Canvas_MouseX)
            y = GetGadgetAttribute(0, #PB_Canvas_MouseY)
            Circle(x, y, 10, RGB(Random(255), Random(255), Random(255)))
            StopDrawing()
          EndIf
        EndIf
      
      Case 1
        If StartDrawing(CanvasOutput(0))
          Box(0, 0, 300, 300, #White)
          StopDrawing()
        EndIf
    EndSelect
    
  EndProcedure
