closing dialog by clicking on it

toxcct

hi everybody, i designed a dialog which i'd like to close by right-click anywhere inside it. For that, i overrided the WM_RBUTTONDOWN an i associated to it the following code :

void CAboutDlg::OnRButtonDown(UINT nFlags, CPoint point) {
this->OnClose();
CDialog::OnRButtonDown(nFlags, point);
}

Unfortunately, it doesn't work :( i've been obliged to create a "OK" button which i hide, and instead of calling OnClose(), i call OnOk() :

void CAboutDlg::OnRButtonDown(UINT nFlags, CPoint point) {
this->OnOk();
CDialog::OnRButtonDown(nFlags, point);
}

It now works, but i don't like this way of contourning the problem. can anybody tell me why my first code doesn't work, and what i could do do resolve th pb ...?

Why not call EndDialog() :-D Ant.

toxcct

work fine :-D thank you anyway, do you have an idea of the reasons OnClose() doesn't work ? would the virtual BOOL CWnd::DestroyWindow(void); have work better too ?

You can do it like this: void CAboutDlg::OnRButtonDown(UINT nFlags, CPoint point) { SendMessage(WM_CLOSE); CDialog::OnRButtonDown(nFlags, point); } and then in OnClose(), you can do the cleanup. OnClose() is called after WM_CLOSE is processed, I guess. So it doesn't actually close the window.

ok. yes, i was calling OnClose() to close, but it is called when the windows is about to be closed... ;) thx

Any reason why OnRButtonDown() is calling OnLButtonDown()? toxcct wrote: Unfortunately, it doesn't work Because EndDialog() is not being called. Take a look at CDialog::OnOK() and CDialog::OnCancel(). Notice how they both call EndDialog().

You would use DestroyWindow() for a modeless dialog and EndDialog() for a modal dialog. OnClose() will call DestroyWindow() anyway IIRC. However without looking I can not recall why they are done differently. Now I will have to look and find out ;) Ant.

From MSDN CDialog::OnOK "If you implement the OK button in a modeless dialog box, you must override the OnOK method and call DestroyWindow from within it. Do not call the base-class method, because it calls EndDialog, which makes the dialog box invisible but does not destroy it." Had to look this up so here for your benefit too. :) Ant.
