A few questions about editbox

[Aaron]

Hi guys,

i'm new here!

The following QM code is from the forum and I need some help:

There is a editorbox in the dialog box, I can drag and drop multiple files into the editing box

#1. Delete lines 27 and 28, it still works. In what case must it be added?

#2. How do I prevent adding duplicate file paths? (Do not display duplicate file paths)

#3. How to control code execution using the Ctrl key:
A. Drag and drop directly: Execute line 30
B. If the Ctrl key is held down during drag and drop, execute Line 32

#4. How to use Ctrl+a hotkey to select all text? here is the C++ implementation code, how to convert it into QM code?
 

Code:

BOOL CMFCApplication1Dlg::PreTranslateMessage(MSG * pMsg)
{
,if (pMsg->message == WM_KEYDOWN)
,{
,,BOOL b = GetKeyState(VK_CONTROL) & 0x80;
,,CWnd *pActiveWnd = GetFocus();
,,DWORD nWndID = 0;
,,if (pActiveWnd)
,,{
,,,nWndID = pActiveWnd->GetDlgCtrlID();
,,}
,,if (b && (pMsg->wParam == 'a' || pMsg->wParam == 'A'))
,,{
,,,SendDlgItemMessage(nWndID, EM_SETSEL, 0, -1);
,,,return TRUE;
,,}
,}
,return CDialog::PreTranslateMessage(pMsg);
}

Solving these problems can help me better understand QM programming, Thanks for any help!
