GUI Window Constrains

Recommended Posts


as already mentioned in the description, I want to make constrains for my GUI-Window according to maximal and minimal width and height.

In C++ - API's I know that as a "Constrains" class of each form where I can set constrains for a GUI window, so that it isn't possible to make it bigger or smaller than the given values.

Is there anyway to set these constrains in AutoIt? (I've already searched but didn't found any which was helpful)

I like to limit the minimal size because the GUI looks broken if you scale it to small.

Thanks for your help!

From my snippets folder (I seem to remember credit goes to martin): :(

#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>

Global $GUIMINWID = 300, $GUIMINHT = 100;set your restrictions here
Global $GUIMAXWID = 800, $GUIMAXHT = 500


$hGUI = GUICreate("Test", 500, 500, -1, -1, BitOR($GUI_SS_DEFAULT_GUI, $WS_MAXIMIZEBOX, $WS_SIZEBOX))


While 1

    Switch GUIGetMsg()
        Case $GUI_EVENT_CLOSE


Func WM_GETMINMAXINFO($hwnd, $Msg, $wParam, $lParam)
    $tagMaxinfo = DllStructCreate("int;int;int;int;int;int;int;int;int;int", $lParam)
    DllStructSetData($tagMaxinfo, 7, $GUIMINWID) ; min X
    DllStructSetData($tagMaxinfo, 8, $GUIMINHT) ; min Y
    DllStructSetData($tagMaxinfo, 9, $GUIMAXWID ); max X
    DllStructSetData($tagMaxinfo, 10, $GUIMAXHT ) ; max Y
    Return 0

Date_Time_Convert -- Easily convert date/time formats, including the language used
ExtMsgBox --------- A highly customisable replacement for MsgBox
GUIExtender -------- Extend and retract multiple sections within a GUI
GUIFrame ---------- Subdivide GUIs into many adjustable frames
GUIListViewEx ------- Insert, delete, move, drag, sort, edit and colour ListView items
GUITreeViewEx ------ Check/clear parent and child checkboxes in a TreeView
Marquee ----------- Scrolling tickertape GUIs
NoFocusLines ------- Remove the dotted focus lines from buttons, sliders, radios and checkboxes
Notify ------------- Small notifications on the edge of the display
Scrollbars ----------Automatically sized scrollbars with a single command
StringSize ---------- Automatically size controls to fit text
Toast -------------- Small GUIs which pop out of the notification area

thank you very much! I've never thought it would be so easy to implement. And I like it because it's the absolutly native Windows-GUI way and not something "self-written" for the behaviour.

Thanks again, I now can use the real benefits of scalable GUI's - also in AutoIt :(
