Hi,

I wrote a wxEVT_KEY_DOWN event handler for the wxTextCtrl control. The handler checks whether user pressed Ctrl+A and if he did - it selects the whole text in the wxTextCtrl.

Here's my handler:

Code: Select all

void MyProgFrame::OnButtonPress(wxKeyEvent& event)
{
    if( (event.GetModifiers() == wxMOD_CONTROL) && (event.GetUnicodeKey() == wxT('A')) )
    {
        TextCtrl1->SetSelection(-1, -1);
    }

    event.Skip();
}

The only thing which annoys me is the beeping while pressing the above combination.

I read about accelerators. According to docs:

For example, you can use an accelerator table to enable a dialog with a multi-line text control to accept CTRL-Enter as meaning 'OK'

So I added this code to my program:

Code: Select all

wxAcceleratorEntry entry(wxACCEL_CTRL, (int)'A', ID_TEXTCTRL1);

wxAcceleratorTable table(1, &entry);

SetAcceleratorTable(table);

and yes - the beeping doesn't occur any more. But now, my handler isn't being called when I press Ctrl+A

Do you know why is that

Accelerators aren't well described in the documentation...

to avoid the beep, avoid calling even.Skip() if the condition matches, so your code should look like this now:

Code: Select all

void MyProgFrame::OnButtonPress(wxKeyEvent& event)
{
    if( (event.GetModifiers() == wxMOD_CONTROL) && (event.GetUnicodeKey() == wxT('A')) )
    {
        TextCtrl1->SetSelection(-1, -1);
        return;
    }

    event.Skip();
}
