Question about a program

[litdev]

Hi,

Another thought on your program

Changes made to the UI (GraphicsWIndow objects) from within event subroutines only take effect after the event subroutine has ended.  Consider the examples below.

Code:

'Main UI thread code
tb = Controls.AddTextBox(50,50)
GraphicsWindow.MouseDown = OnMouseDown
'Event Subroutines
Sub OnMouseDown
  Controls.SetTextBoxText(tb,"Hello World")
  Program.Delay(3000) 'Time consuming work
EndSub

Code:

'Main UI thread code

tb = Controls.AddTextBox(50,50)
GraphicsWindow.MouseDown = OnMouseDown

'Game loop

While ("True")
  If (clicked) Then
    Controls.SetTextBoxText(tb,"Hello World")
    Program.Delay(3000) 'Other time consuming work
    clicked = "" 'Reset handled flag
  EndIf
 
  Program.Delay (100) 'Don't mash cpu
EndWhile

'Subroutines

Sub OnMouseDown
  clicked = "True"
EndSub
