Autogui Style Dynamically

[CyberSlug]

Can the style and exStyle of a control be set dynamically? I want to toggle word wrap on an edit control.....

My workaround is to create two Edit controls (one with wordwrap, one without) and only have one visible at a time.

expandcollapse popup

Global $title = "text editor foo"
Global $typeface = "Courier New"

Global $wrapping = 1
; stores status of word wrap; 1 = disabled, 2 = enabled
; the $wrap checkbox control is read and note that 0=disabled, 1=enabled

Opt("GuiNotifyMode",1)
GUICreate($title, 440, 280, 100, 100)
WinActivate($title)

Global $txt1 = GUISetControl("edit", "", 0, 30 ,430 ,220)
Global $txt2 = GUISetControl("edit", "", 0, 30 ,430 ,220, 0x50200104, 0x00000200)
Global $wrap = GUISetControl("checkbox", "Word wrap", 5,5, 400,20)

ControlCommand($title,"", "Word wrap", "Check", "")
GUISetControlFont($txt1, 10, 400, $typeface)
GUISetControlFont($txt2, 10, 400, $typeface)

GUIShow()

;loop until user clicks the close button
while 1
 ;ToolTip(GUIMsg(0), 0,0)
   sleep(100)
   If GuiMsg(0) = -3 Then
      If GUIRead( Eval("txt" & $wrapping) ) <> "" Then MsgBox(4096,"","Quitting")
      ExitLoop
   EndIf
   $w = 1 + ControlCommand ($title,"", "Word wrap", "IsChecked", "")
   If $w <> $wrapping Then
    ; set controls to contain same text, then toggle which is visible
      $text = GUIRead( Eval("txt" & $wrapping) )
      ControlSetText ($title,"", "Edit"&$w, $text)
      ControlShow ($title,"", "Edit"&$w )
      ControlHide ($title,"", "Edit"&$wrapping )
      $wrapping = $w
   EndIf
Wend
Exit

I don't think so, because only some control can be change with special Windows API.

Which Style ExStyle are you thinking about?

I can change the style in 2 lines, provided you already have the HWND to the window/control and the new style to add...

LONG style = GetWindowLong(hWnd, GWL_STYLE);
SetWindowLong(hWnd, GWL_STYLE, style | newStyle);

And I can do the same for extended styles...

LONG exStyle = GetWindowLong(hWnd, GWL_EXSTYLE);
SetWindowLong(hWnd, GWL_EXSTYLE, exStyle | newExStyle);

And I usually use this to remove a style:

LONG style = GetWindowLong(hWnd, GWL_STYLE);
if (style & styleToRemove)
    SetWindowLong(hWnd, GWL_STYLE, style ^ newStyle);
// If the style isn't there, nothing needs to be done...

Larry, here is my thoughts on that. If you are messing with something, you should know what you are doing with it. If you try to mess with something you don't understand and you screw something up, well, it sucks to be you then, cause I would of had enough sense to know what I'm doing first.

Agreed.

Anyway, how is this any different from calling GUISetControl with style and exStyle? You allow the user that much control all ready

[Valik]

I agree, except I don't think there needs to be seperate functions for controls and Windows. Just a GetStyle, SetStyle, GetStyleEx, SetStyleEx should be sufficient.

Edit: Never mind that. I realize why you have to do it that way now (Forgot we can't get HWND's of controls (yet)).

Larry, Valik,

I add the support in GuiWrite(controlref,state,text,style,exstyle)

is it OK for you?
