Hello

I'm poting you this message and sure you don't need to reply or help me, I would just be glad if you can

As I told in the forum post, my aim is to develop an MFC-based object which would act like, for instance, CHtmlView: on the programmer side, the only action that would need to be done would be to call CMyClass::Create(dwStyle, rect, parentDialog, staticCtrlID) and this would create the control, in any kind of control (static text, edit box, ...). Also, the control would take over the default keyboard and mouse actions on the dialog and therefore, for example, clicking on the class "window" and then pressing the arrow buttons on the keyboard would only make the class take an action.

This is the point where I'm stuck: how can I make this class get created on any kind of static control and second (more importantly) how do I make it capture all actions once clicked on (and release it back once the user clicks somewhere else)?

Thank you

Hello

It's just to tell you that I've solved the issue... Here's how it goes:

Problem: when there's a control in a dialog box replacing a STATIC resource, it will lose focus as soon as a key is pressed (things move in the dialog box) and it will never receive the OnKeyDown call.

Reason: STATIC is not supposed to be doing input/output, as a result it cannot receive keyboard events. As a result, you won't receive the OnKeyDown call (even if you do put it in the message map) and any pressed key, since not captured by the STATIC, will get dispatched to the parent (the dialog box) and this will make it take the default action -changing the selected button.

Solution: in the class that wants to go into a STATIC, overload the PreTranslateMessage, OnLButtonDown and OnRButtonDown methods (you also need to specify the mouse actions in the message map). PreTranslateMessage shall check if( pMsg->message == WM_KEYDOWN ), and in this case call OnKeyDown followed by CWnd::PreTranslateMessage and return TRUE (so the message doesn't get dispatched). If not, it shall return whatever CWnd::PreTranslateMessage returns. In the mouse handling methods, call SetFocus to get the focus when clicked.

New problem: the call you do to OnKeyDown is ignored (in classes that inherit from our base class, at least).

Reason: Don't know why...

Solution: Create a new virtual OnKeyDown method which would have a different signature from the original method (for example, one that only takes the nChar argument) and call that one. Now, put the key handling stuff in that new OnKeyDown method.

The solution therefore doesn't require you to overload CDialog::PreTranslateMessage or do other things like that. Note that the modification done to PreTranslateMessage is also very small, which makes that the overall behaviour of the control as well as the dialog box remains the same...
