Lock gui width when resize

7 posts in this topic

Hi, its possible to lock a GUI width only allowing to change is height?

And how can I set the minimal size as the window can be? yes I look in the help file and just found resize dock positions, etc...not any way to lock

I also tried with GUICtrlSetResizing(-1,$GUI_DOCKWIDTH), but nothing changed...

thanks in advance


Heroes, there is no such thing

One day I'll discover what IE.au3 has of special for so many users using it.
C'mon there's InetRead and WinHTTP, way better

You can do it this way.

; Add this line near the top of your script
GUIRegisterMsg($WM_GETMINMAXINFO, "_WM_GETMINMAXINFO") ; Monitors resizing of the GUI


Func _WM_GETMINMAXINFO($hWnd, $Msg, $wParam, $lParam) ; used to limit the minimum size of the GUI
    #forceref $hWnd, $Msg, $wParam, $lParam
    Local $iWidth = 300 ; minimum width setting
    Local $iHeight = 600 ; minimum height setting
    If $hWnd = $YourGUI
        Local $tagMaxinfo = DllStructCreate("int;int;int;int;int;int;int;int;int;int", $lParam)
        DllStructSetData($tagMaxinfo, 7, $iWidth) ; min width
        DllStructSetData($tagMaxinfo, 8, $iHeight) ; min height
                DllStructSetData($tagMaxinfo, 9, $iWidth) ; max width
                DllStructSetData($tagMaxinfo, 10, 99999) ; max height
        Return $GUI_RUNDEFMSG
    EndIf
EndFunc   ;==>_WM_GETMINMAXINFO

Add this to the script and change the values to what you want your GUI to be sized to, also change the variable $YourGUI in this line "If $hWnd = $YourGUI" to the handle to your GUI.

Thank you sir, works great :D

In minimum width I need to set my gui width + 16, and for height + 38, any reasons for this? :o

The borders take up space, and the title bar if any takes up more space. This function limits the entire GUI, while your GUICreate only specifies the client area.

never thought in that

btw, there's any reason by when I reasize my gui, every controls (labels, inputs, groups, buttons, pic...) blink?

They get painted again and again and hence you see the blink, you can use the $WS_EX_COMPOSITED ex-style upon creating the GUI it would allow double-buffer for painting and hence you wont see the flickering, but the style has some issues, use with caution

Regards :)


My code:

PredictText: Predict Text of an Edit Control Like Scite. Remote Gmail: Execute your Scripts through Gmail. StringRegExp:Share and learn RegExp.

Run As System: A command line wrapper around PSEXEC.exe to execute your apps scripts as System (LSA). Database: An easier approach for _SQ_LITE beginners.

MathsEx: A UDF for Fractions and LCM, GCF/HCF. FloatingText: An UDF for make your text floating. Clipboard Extendor: A clipboard monitoring tool. 

Custom ScrollBar: Scroll Bar made with GDI+, user can use bitmaps instead. RestrictEdit_SRE: Restrict text in an Edit Control through a Regular Expression.

Thanks for the explanation :), I use it as ex-style and my gui stop responding :s

this is the styles I applied:

GUICreate("Title", width, height, -1, -1,BitOR($GUI_SS_DEFAULT_GUI, $WS_SIZEBOX, $WS_THICKFRAME, $WS_TABSTOP),$WS_EX_COMPOSITED)
