Aspect ration of program

[MariusN]

Hi folks...I have a small problem. How can i keep my aspect-ratio of my program to automatically adjust to any screen resolution?

For example, sometimes if a customer's resolution of a screen differs from others, my program will either show the complete program, or somehow the program will be "cut-off" at the edges, or some info wont even be displayed. Its not only the GUI that is "out-of-aspect"- ratio, but also my buttons, text, etc that's part of my compiled script...

Anyone?

You can take the current desktop width and height using the macros @DesktopWidth and @4DesktopHeight and calculate the maximum GUI size with the expected ratio.

MariusN,

You might want to create your GUI for the lowest resolution you are likely to face and allow it to be resized but keeping the same aspect ratio - like this:

expandcollapse popup

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

; Set resize mode for controls
Opt("GUIResizeMode", $GUI_DOCKAUTO)

$hGUI = GUICreate("Test", 500, 300, -1, -1, BitOR($WS_SIZEBOX, $WS_SYSMENU))

$cButton_1 = GUICtrlCreateButton("Test 1", 10, 10, 80, 30)
$cButton_2 = GUICtrlCreateButton("Test 2", 10, 50, 80, 30)

GUISetState()

GUIRegisterMsg($WM_SIZING, "_WM_SIZING")

While 1
    Switch GUIGetMsg()
        Case $GUI_EVENT_CLOSE
            Exit
    EndSwitch
WEnd

Func _WM_SIZING($hWnd, $iMsg, $wParam, $lParam)

    #forceref $iMsg, $wParam, $wParam

    If $hWnd = $hGUI Then

        Local $iNew_H, $iNew_W

        Local $sRect = DllStructCreate("Int[4]", $lParam)
        Local $iLeft = DllStructGetData($sRect, 1, 1)
        Local $iTop = DllStructGetData($sRect, 1, 2)
        Local $iRight = DllStructGetData($sRect, 1, 3)
        Local $iBottom = DllStructGetData($sRect, 1, 4)
        ; Keep the same aspect ratio
        Switch $wParam ; drag side or corner
            Case 1, 2 ; $WMSZ_LEFT, $WMSZ_RIGHT
                $iNew_H = Int(($iRight - $iLeft) * 300 / 500)
                DllStructSetData($sRect, 1, DllStructGetData($sRect, 1, 2) + $iNew_H, 4)
            Case Else
                $iNew_W = Int(($iBottom - $iTop) * 500 / 300)
                DllStructSetData($sRect, 1, DllStructGetData($sRect, 1, 1) + $iNew_W, 3)
        EndSwitch
    EndIf

EndFunc

You will notice the font remains the same size. You can change that by adding another handler - let me know if you want to see how.

MariusN,

Do you want the font size changing code?
