Retaining higlighted text in multi-line edit contro when another control is clicked

[philw]

Hi,

I have three controls in a window, a multi-line edit control, a list and a button. I want to highlight a few lines of text in the edit control, click on an item in the list and then click on the button. When the button is clicked, a function applies the item selected in the list to the highlighted text.

However, as soon as I click on the list, the highlighting in the edit control vanishes, and _GUICtrlEdit_GetSel returns an empty string. Any way of preventing this?

Thanks!

Try this:

expandcollapse popup

#include <GuiConstantsEx.au3>
#include <WindowsConstants.au3>
#include <GuiEdit.au3>

Global $aSelect

$hGUI = GUICreate("Test", 300, 280)

$ctlList = GUICtrlCreateList("MyListBox", 10, 10, 280, 100)

$ctlEdit = GUICtrlCreateEdit("Hello world!", 10, 120, 280, 100)

$button = GUICtrlCreateButton("Test", 11, 245, 75, 23)

GUIRegisterMsg($WM_COMMAND, "WM_COMMAND")

GUISetState()

Do
Until GUIGetMsg() = -3

Func WM_COMMAND($hWnd, $Msg, $wParam, $lParam)
    Local $iIDFrom = BitAND($wParam, 0x0000FFFF)
    Local $iCode = BitShift($wParam, 16)
    
    Switch $iIDFrom
        Case $ctlEdit
            Switch $iCode
                Case $EN_KILLFOCUS
                    $aSelect = _GUICtrlEdit_GetSel($iIDFrom)
                Case $EN_SETFOCUS
                    If IsArray($aSelect) Then
                        _GUICtrlEdit_SetSel($iIDFrom, $aSelect[0], $aSelect[1])
                        $aSelect = 0
                    EndIf
            EndSwitch
    EndSwitch
    
    Return $GUI_RUNDEFMSG
EndFunc

ES_NOHIDESEL

When ES_NOHIDESEL is specified for an edit control, selected text remains highlighted when the edit control does not have the focus. Normally, without ES_NOHIDESEL specified, an edit control "hides" the selection when it loses focus. In other words, the selection is not highlighted, but the text still appears as normal.
