I'm trying to catch when the user pressed Ctrl + A on the keyboard. But when the Ctrl qualifier
is set, BFM_INPUT_ASC is an empty string.

The following is the output for the following actions:

Click
Pressing 'a'
Click
Pressing Ctrl + 'a'

MaskExportTreeModel::InputEvent
BFM_INPUT_VALUE: 1
BFM_INPUT_ASC: 
MaskExportTreeModel::InputEvent
BFM_INPUT_VALUE: 1
BFM_INPUT_ASC: a
MaskExportTreeModel::InputEvent
BFM_INPUT_VALUE: 1
BFM_INPUT_ASC: 
MaskExportTreeModel::InputEvent
BFM_INPUT_VALUE: 1
BFM_INPUT_ASC: 
CTRL!!

And this is the corresponding code:

Bool MyTreeViewFunctions::InputEvent(void* root, void* ud, GeUserArea* area,
                                     const BaseContainer& msg) {
    GePrint(__FUNCTION__);
    GePrint("BFM_INPUT_VALUE: " + LongToString(msg.GetLong(BFM_INPUT_VALUE)));
    GePrint("BFM_INPUT_ASC: " + msg.GetString(BFM_INPUT_ASC));
  
    if (msg.GetLong(BFM_INPUT_QUALIFIER) & QCTRL) {
        GePrint("CTRL!!");
    }
  
    return TreeViewFunctions::InputEvent(root, ud, area, msg);
}

Pressing Ctrl alone does not trigger an Input event, only when pressing Ctrl + 'some key' triggers
the method. But the key pressed together with the qualifier is not given. How can I catch the
Ctrl + 'a' key-press correctly?

Thanks!

This should give you the ASCII decimal value for the key:

LONG chn = msg.GetLong(BFM_INPUT_CHANNEL);

Thank you David, that's it!
