Dialog activation issue (hard problem?)

Hi Everyone,

I have this problem for a long time and hope to find a solution for it. It is very cumbersome to describe, so
please bear with me.

I have developed a CAD application using WTL. The screen is divided into two parts. The main window on left
size is a 3D canvas. The right side is 3DS like interface that uses an embedded tab control/view to host
various GUI pages. Each page hosts one or more dialogs which itself host various UI wedgets, eg. radio
button, edit control.

The problem: every time I want access any non-hot tracking UI wedgets, I have to double click it: 1st time to
activate the dialog, 2nd time to actually use the GUI control itself.

This is very annoying as user would not expect double clicks. My way of getting around this is to use
SetCapture for mouse and SetFocus for keyboard on mouse move or mouse enter event. I do this both for the
embedded dialogs and for the 3D canvas window. That is,when mouse enters the embedded dialogs,
SetCapture and SetFocus is called to set focus/capture to the dialog where mouse cursor is. When the mouse
is moved back into the 3D canvas, I do the same. This introduce another annoyance: when the mouse cursor is
moved back to 3D canvas, any floating non-modal dialog will NOT get focus, unless the mouse cursor is set to
a hot-tracking widget (e.g. a button that reacts to mouse enter event) in the non-modal dialog. This means
I have to make all controls in the non-modal dialog track with the
mouse movement. But as the application must run as an ActiveX control in another host, I have no controls to
any non-modal dialog displayed by the 3rd party host.

Is there any way to get around this problem? I can give you access to my software if my explanation of the
problem is not clear enough.

I know this is probably not WTL problem per se. But as the entire application is built with WTL, I think my
question is still relevant. Any help is appreciated.

Re: Dialog activation issue (hard problem?)

Dennis,

It sounds like you should be able to solve this by putting both "parts" 
into the same top-level window. What classes are you using for the two 
parts? I think you might need to move from a Dialog to a different 
window type, but otherwise, the only thing you should have to do is 
create a common parent to both "parts". Windows likes embedding windows 
within windows...

Another option to explore would be to handle the activation click on the 
dialog box explicitly, passing it through to the appropriate child 
widget, rather than capturing the mouse. I'm not fluent in the details 
it would take to do that, but I'd try it if switching from a dialog and 
making a common parent doesn't work.

RE: Dialog activation issue (hard problem?)


Hi Joe,
Thanks for the suggestions! The number of dialogs involved is over 15. So converting each of them into a
CWindow is out of question due to amount of work involved. The dialogs and 3D canvas do share the same parent
but they do not live on same levels.
Handing activation click sounds a way to go. Do you know what message is translated into dialog activation
click? WM_MOUSEDOWN?
Thanks again,
Dennis

RE: Dialog activation issue (hard problem?)


Found this article:http://chabster.blogspot.com/2010/03/focus-and-window-activation-in-win32.html
It seems I need to handle WM_ACTIVATE? i.e.,  on receving one the messages, instead of passing the control to
default dialog procedure, I need to call SetFocus on the GUI widget that was clicked?
Thanks,
Dennis

Mainframe menu position (as in explorer)

Hi,
I'm creating an application which has a breadcrumb which looks similar to explorer's. It starts with the
control menu hidden. When the user presses "Alt" the menu toggles between visible/hidden. I'm using

SetMenu(mainmaun) and SetMenu(NULL)

The problem is the menu appears *above* my own breadcrums, and I can't find a way to make it appear below it(as
in explorer). Is there any way to position the menu?

thanks, Dan

In Explorer, it's not a real menu bar (the kind you manage with SetMenu). It's actually a toolbar with its
buttons cleverly custom-drawn to look like menu items. You can see that with Spy++. It's all smoke and mirrors.

Thank you very much, I'll try and implement something like this.
