Hello,
Can anyone tell me if I am using this correctly
Thanks
Ken
Code: Select all
;Capture mousedown and abort events
CallFunction (0,"VCSetAlertAppDll",@iError,"Test","DrawLine",ALERT_APP_UTOOL_MOUSEDOWN)
;User tool prompt
CallFunction (1,"VCSetUserTool",2,"DrawLine","Enter lower left corner")
CallFunction (1,"VCSetPrompt",1,"Enter lower right corner")
Repeat
WaitWindowEvent()
Event = EventType()
If Event = #PB_EventType_LeftClick
;Get 1st mouse down point
;CallFunction (0,"VCGetUserToolLBDown",@iError,StartLine())
MessageRequester("Test", "MouseClick1", 0)
Else
Delay(1) ; No event, let the others apps get some CPU time too !
EndIf
Until ToolState = 10

It should more look like:
Code: Select all
;Capture mousedown and abort events
CallFunction (0,"VCSetAlertAppDll",@iError,"Test","DrawLine",ALERT_APP_UTOOL_MOUSEDOWN)
;User tool prompt
CallFunction (1,"VCSetUserTool",2,"DrawLine","Enter lower left corner")
CallFunction (1,"VCSetPrompt",1,"Enter lower right corner")
OpenWindow(0,0,0,230,90,#PB_Window_SystemMenu|#PB_Window_ScreenCentered,"Event handling example...")
Repeat
Event = WaitWindowEvent()
; EventType() is only used with Gadgets...
; #PB_EventType_LeftClick is only used with Gadgets...
If Event = #WM_LBUTTONDOWN ;this is a WinAPI constant
;Get 1st mouse down point
;CallFunction (0,"VCGetUserToolLBDown",@iError,StartLine())
MessageRequester("Test", "MouseClick1", 0)
Else
Delay(1) ; No event, let the others apps get some CPU time too !
EndIf
Until EventID = #PB_Event_CloseWindow
; don't know what this should be -> Until ToolState = 10
hope this helps a bit...

No need for
in the updated code when using
because this command waits for an event then continues the main loop. If this was used
the the delay would be necessary because this is nothing to halt the program taking 100% cpu time.

And you should only use Delay(1) if the result of WindowEvent() = 0,
otherwise it'll slow down the updating of all gadgets on your window.
