Almost autosize all listview columns?

Recommended Posts



I would like to have this kind of behaviour... but I'm not sure how to code it. Any suggestions appreciated.

(1) ListView autosizes all columns (that is what I am doing now)

works great except if there is not enough room for all the text in the items.

(2) Then it shrinks the first columns and leaves the last one wide

new logic desired:

- If (and only if) (2) occurs then I would like to autosize all columns except the last one. The last one then will either be shrunk to fit the remaining space... or it will be autosized wide enough for its text, but not to the detriment of the previous columns. That is, it would overflow to the right past the width of the window, so I would have to scroll to see all of the text.

anyone have some ideas?

I use this:

#include <GuiConstants.au3>

$Main_GUI = GUICreate("ListView Set Equel Column Width", 340, 260, -1, -1, $WS_OVERLAPPEDWINDOW)

$ListView = GUICtrlCreateListView("col1|col2|col3", 20, 30, 300, 150, _

GUICtrlCreateListViewItem("line1|data1|more1", $ListView)
GUICtrlCreateListViewItem("line2|data2|more2", $ListView)
GUICtrlCreateListViewItem("line3|data3|more3", $ListView)
GUICtrlCreateListViewItem("line4|data4|more4", $ListView)
GUICtrlCreateListViewItem("line5|data5|more5", $ListView)

$Set_Equel_Button = GUICtrlCreateButton("Set Equel Width", 20, 190, 100, 20)
$Set_Full_Button = GUICtrlCreateButton("Set Full Width", 20, 220, 100, 20)


GUIRegisterMsg($WM_SIZE, "WM_SIZE")

While 1
    $iMsg = GUIGetMsg()
    Switch $iMsg
        Case $GUI_EVENT_CLOSE
        Case $Set_Full_Button, $GUI_EVENT_MAXIMIZE, $GUI_EVENT_RESTORE
            _GUICtrlListView_SetEquelColWidth($Main_GUI, $ListView, 1)
        Case $Set_Equel_Button
            _GUICtrlListView_SetEquelColWidth($Main_GUI, $ListView, 0)

Func _GUICtrlListView_SetEquelColWidth($hWnd, $hLV, $iFullMode=1)
    If Not IsHWnd($hLV) Then $hLV = ControlGetHandle($hWnd, "", $hLV)
    If @error Then Return SetError(1, 0, -1)
    Local $hUser32DllOpen = DllOpen("user32.dll")
    If $hUser32DllOpen = -1 Then Return SetError(2, 0, -1)
    Local $LV_Header = DllCall($hUser32DllOpen, "long", "SendMessage", "hwnd", $hLV, "int", $LVM_GETHEADER, "int", 0, "int", 0)
    If @error Then Return SetError(3, 0, -1)
    ;Local Const $HDM_GETITEMCOUNT = 0x1200
    Local $sItmsCnt = DllCall($hUser32DllOpen, "long", "SendMessage", "hwnd", $LV_Header[0], "int", 0x1200, "int", 0, "int", 0)
    If @error Then Return SetError(4, 0, -1)
    Local $Columns_Count = $sItmsCnt[0]
    Local $iLV_Width = 0
    Switch $iFullMode
        Case 0
            Local $Columns_Width = 0
            Local $GetColumns_Width
            For $i = 0 To $Columns_Count
                $GetColumns_Width = DllCall($hUser32DllOpen, "long", "SendMessage", _
                    "hwnd", $hLV, "int", $LVM_GETCOLUMNWIDTH, "int", $i, "int", 0)
                $Columns_Width += $GetColumns_Width[0]
            $iLV_Width = $Columns_Width / $Columns_Count
        Case 1
            Local $sLV_Width = ControlGetPos($hWnd, "", $hLV)
            If @error Then Return SetError(5, 0, 0)
            $iLV_Width = ($sLV_Width[2]-10) / $Columns_Count
        Case Else
            Return SetError(6, 0, -1)
    For $i = 0 To $Columns_Count
        DllCall($hUser32DllOpen, "long", "SendMessage", "hwnd", $hLV, "int", $LVM_SETCOLUMNWIDTH, "int", $i, "int", $iLV_Width)

Func WM_SIZE($hWndGUI, $MsgID, $WParam, $LParam)
    ;По каким то причинам функция не срабатывает корректно при разворачивании/восстановлении,
    ;поэтому пусть стандартный обработчик справляется с этими событиями ($GUI_EVENT_MAXIMIZE, $GUI_EVENT_RESTORE)..
    _GUICtrlListView_SetEquelColWidth($hWndGUI, $ListView, 1)
