Auto Resizing of ListView in GUI Window

MikahS · October 23, 2014

Hello AutoIt community,

I have a question for you. I have 3 separate ListViews which need to be auto sized to the GUI width / height. I've looked around the forum for a day or two and have tried using the WM_SIZE method, which after playing with it, I've realized that not everyone's screen is the same and hardcoding it could be troublesome.

So, I'm thinking I need to come up with a better way of resizing my ListViews to my GUI. Does anyone have any suggestions on different ways of achieving this goal?

Example script:

#Region ;**** Directives created by AutoIt3Wrapper_GUI ****
#AutoIt3Wrapper_Icon=
#AutoIt3Wrapper_Outfile=
#AutoIt3Wrapper_Res_Comment=
#AutoIt3Wrapper_Res_Description=
#AutoIt3Wrapper_Res_Fileversion=
#AutoIt3Wrapper_Run_Au3Stripper=y
#Au3Stripper_Parameters=/so
#EndRegion ;**** Directives created by AutoIt3Wrapper_GUI ****

MikahS,

I would create disabled labels behind the ListViews which resize automatically and then resize the ListViews to fit the labels:

#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>
#include <GuiScrollBars.au3>
#include <GUIListViewEx.au3>
#include <EditConstants.au3>

Local $List1, $List2, $List3, $List4, $lp_Buffer = 0
Local $List1Ex, $List2Ex, $List3Ex

Global $GUIhandle, $cLabel_1, $cLabel_2, $cLabel_3

GUI()

GUIRegisterMsg($WM_SIZE, "WM_SIZE")

_GUIScrollBars_EnableScrollBar(ControlGetHandle("", "", $List2), $SB_BOTH, $ESB_DISABLE_BOTH)
_GUIScrollBars_EnableScrollBar(ControlGetHandle("", "", $List3), $SB_BOTH, $ESB_DISABLE_BOTH)


While 1
    $msg = GUIGetMsg()

You are one smart cookie Melba

It works perfectly as expected. Only, one minor detail.

If the window is maximized it will stay the same, and will only change sizes when you are manually resizing the window. Any thoughts?

Melba23 · October 23, 2014

MikahS,

You are one smart cookie Melba

Thanks. :blush:

As to the "minor detail" - I suggest looking for the maximize and restore messages and running the same function when they occur.

MikahS · October 23, 2014

I tried using GUIRegisterMsg($WM_SYSCOMMAND, 'WM_SIZE'). It does the same behavior for maximizing, but tries to expand everything when it is then restored.

I must be missing something.. :geek:

EDIT: Also tried

GUIRegisterMsg(0xF030, "WM_SIZE")
GUIRegisterMsg(0xF020, "WM_SIZE")
GUIRegisterMsg(0xF120, "WM_SIZE")

MikahS,

Try this - you need to wait until the window has been maximized/restored before you resize which is why I use a flag in the idle loop:

Global $GUIhandle, $cLabel_1, $cLabel_2, $cLabel_3

Global $bSysMsg = False

GUI()

GUIRegisterMsg($WM_SIZE, "_WM_SIZE")
GUIRegisterMsg($WM_SYSCOMMAND, "_WM_SYSCOMMAND")

_GUIScrollBars_EnableScrollBar(ControlGetHandle("", "", $List2), $SB_BOTH, $ESB_DISABLE_BOTH)
_GUIScrollBars_EnableScrollBar(ControlGetHandle("", "", $List3), $SB_BOTH, $ESB_DISABLE_BOTH)


While 1
    $msg = GUIGetMsg()
    Switch $msg
        Case $GUI_EVENT_CLOSE
            Quit()

Very good, but there is no check for double-click on window title events. Here is the fix:

Func _WM_SYSCOMMAND($hWnd, $msg, $wParam, $lParam)

    Const $SC_MAXIMIZE = 0xF030
    Const $SC_RESTORE = 0xF120
    ;Restore via double-click on title window
    Const $SC_RESTORE2 = 0xF122
    ;Maximize via double-click on title window
    Const $SC_MAXIMIZE2 = 0xF032

    Switch $wParam
        Case $SC_MAXIMIZE, $SC_RESTORE, $SC_RESTORE2, $SC_MAXIMIZE2
            $bSysMsg = True
    EndSwitch
    
EndFunc

AckerMAN,

Welcome to the AutoIt forums.

Thanks for adding the extra code - I did not even know that you could do that!
