[18 Mar 2009] losing focus with Filerequest

Hello, I have several buttons on my Display. When I use the Function "FileRequest" and answer the requester with OK or Cancel, the "MouseOver"-Event behaves strange. After answering "FileRequest" the only button where Mouseover still works is the button where the "FileRequest" is behind. When moving the mouse over other buttons no MouseOver-Event is triggered. This can be changed when doing LMB into the display.

Is there a way around this, or is this expected behaviour?

CodeSnippets:

Code: Select all

Function p_Hover(msg)
    DisplayTextObject(msg.id,#CENTER,#BOTTOM)
EndFunction

Function p_UnHover(msg)
    Undo(#TextObject,msg.id)
EndFunction 

Function p_prepMenu()
   evtmatch = {OnMouseDown = p_HandlerFunc, OnMouseOver = p_Hover, OnMouseOut = p_UnHover}
   /*1 Load*/
   DisplayBrush(1,10,15)
   MakeButton(1,#SimpleButton, 10,15,24,24,evtmatch)
   /*2 Save*/
   DisplayBrush(2,40,15)
   MakeButton(2,#SimpleButton, 40,15,24,24,evtmatch)
   /*3 Import*/
   DisplayBrush(3,70,15)
   MakeButton(3,#SimpleButton, 70,15,24,24,evtmatch)
EndFunction 

Kind regards GMKai

Is the Hollywood window active or inactive? MouseOver etc. events will only work when the Hollywood window has the focus. If an other window is active (e.g. the window of the file requester), no mouse events will be handled.

Hallo Andreas,

the described behaviour appears after the requester is answered. Thus the requester is closed and can't be active. The focus is at the Hollywood-Window, but Mouse-Over works only for the Button with the requester, Mouse-Over for other buttons does not work until a LMB into the Hollywood-window.

An exception to this rule is if an interval is running. The MouseOver events will be triggered even when the Hollywood window is inactive if you add something like this to the code:

Code: Select all

Function p_InterFunc()
EndFunction
SetInterval(1, p_InterFunc, 40)

The interval frequency determines how quickly the MouseOver and MouseOut events will be noticed with the inactive window. This is probably an unintended "feature" or "bug" (depending on whether or not you like this behavior).

True... if no one complains about this behaviour then let's call it a feature

Hallo Andreas,

the described behaviour appears after the requester is answered. Thus the requester is closed and can't be active. The focus is at the Hollywood-Window, but Mouse-Over works only for the Button with the requester, Mouse-Over for other buttons does not work until a LMB into the Hollywood-window.

That's weird. Do you have a script that demonstrates this behaviour? Please try to make it as small as possible

Hallo Andreas,

you get 3 white boxes, the leftmost opens the requester. When clicking "ok" in the requester mouse-over gets corrupted. It still works for the clicked button, but the others don't get highlighted.

here the example:

Code: Select all

@VERSION 4,0
CtrlCQuit(True)
EscapeQuit(False)
EnableLayers()

Function p_HandlerFunc(msg)
     Switch(msg.id)
      Case 1:
        p_LoadProject()
      Case 2:
        p_SaveProject()
      Case 3:
        p_ImportProject()
     EndSwitch
EndFunction

Function p_Main()
   Repeat
        WaitEvent
   Forever
EndFunction

Function p_prepMenu()
    evtmatch = {OnMouseDown = p_HandlerFunc, OnMouseOver = p_Hover, OnMouseOut = p_UnHover}
    /*1 Load*/
    DisplayBrush(1,10,15)
    MakeButton(1,#SimpleButton, 10,15,24,24,evtmatch)
    /*2 Save*/
    DisplayBrush(2,40,15)
    MakeButton(2,#SimpleButton, 40,15,24,24,evtmatch)
    /*3 Import*/
    DisplayBrush(3,70,15)
    MakeButton(3,#SimpleButton, 70,15,24,24,evtmatch)
EndFunction

Function p_MainMenu()
    DisplayBGPic(1)
EndFunction

Function p_LoadBrushes()
    /*LoadBrush(1,"tbimages:backup_g")
    LoadBrush(2,"tbimages:save_g")
    LoadBrush(3,"tbimages:import_g")
    */
    CreateBrush(1,24,24,#WHITE)
    CreateBrush(2,24,24,#WHITE)
    CreateBrush(3,24,24,#WHITE)
EndFunction

Function p_Hover(msg)
    DisplayTextObject(msg.id,#CENTER,#BOTTOM)
EndFunction

Function p_UnHover(msg)
    Undo(#TextObject,msg.id)
EndFunction

Function p_prepStrings()
    SetFontColor(#WHITE)
    SetFont("topaz.font",11)
    CreateTextObject(1,"Load")
    CreateTextObject(2,"Save")
    CreateTextObject(3,"Import")
EndFunction

Function p_LoadProject()
    f$=FileRequest("Load Project","hsmdb")
    If f$ <> ""

    EndIf()
EndFunction

Function p_SaveProject()

EndFunction

Function p_ImportProject()

EndFunction

Function p_NewProject()

EndFunction

p_prepStrings()
p_LoadBrushes()
p_prepMenu()
p_main()

Hallo Andreas,

you get 3 white boxes, the leftmost opens the requester. When clicking "ok" in the requester mouse-over gets corrupted. It still works for the clicked button, but the others don't get highlighted.

Ok, this seems to be a bug. You can circumvent it by using the "OnMouseUp" in your evtmatch table instead of "OnMouseDown", e.g.:

evtmatch = {OnMouseUp = p_HandlerFunc, OnMouseOver = p_Hover, OnMouseOut = p_UnHover}

By the way, you should always use "OnMouseUp" to catch mouse clicks on a button. "OnMouseDown" is only useful if you want to display a highlight state of the button while the mouse button is down. If you only want to catch a mouse click, always use "OnMouseUp" because that triggers when the mouse button is up again. And correct buttons should never trigger before the mouse button is up again! (just try in any GUI you like; a button will not trigger before the mouse button is released)

Hallo Andreas,

thanks for the hint with using OnMouseUp it works as expected.

Thanks alot. Kai
