Printable View
Hi,
I have formviews with their own toolbars.
The problem now is that I cannot get a messagehandler for the toolbar in the formviews but I have to make it in the Mainfrm or the icons won't look enabled.
I have to put the messagehandler into the formview where it belongs and not into the mainfrm where there is already another one for its own toolbar.
Can someone help with this ?
Firstly, why would you create tool bar in a view. Usually frame windows have build-in functionality to handle toolbars and routing command messages.
If you place a toolbar in a view, you may encounter UI updating problems, if update handlers for given command ID are placed in other windows. In addition, changing default routing by overriding OnCmdMsg, can be a culprit. That may prevent from enabling certain buttons.
Views are hosted in frames and MFC routing mechanism ensures proper UI updating. Is your application MDI or SDI?
I would suggest posting entire project here so we can see what is a causing a problem.
Well, its not a normal view but a formview and to use a toolbar there is the most elegant way to solve what I want.Quote:

But I need the formview to handle its own toolbars.Quote:

Thanks for the advice, I'll make sure that each ID is only used once.Quote:

The project is unfortunately huge so I cannot post it but what I want is actually quite simple. I just have a SDI MFC App with a formview and many dialogs that are switched by the big toolbar in mainframe (which works nice) but each of those CDialogs has toolbars too.Quote:

And I cannot get those toolbars to work.
They don't enable (unless I put the handler in mainfrm where it doesn't belong) and they cannot be clicked to call functions in the dialog.
I hope that makes it clearer.
A formview (of class CFormView) is also a very "normal" view as well as the others derived from CView.Quote:

If you have multiple message (or UI update) handlers for the same command ID you may experience problems you have described."elegant way" is very subjective. Consider using one common toolbar and specific one for a given view.Quote:

Not really since we have just encountered new element in your post that has not been mentioned before. I know I maybe sound (look) annoying but from my experience, in cases like that working on the project together saves time and makes thread considerably shorter.Quote:

For example:
How dialogs are displayed? Are they modal or modeless? Are they children of any windows or just pop up dialogs. If popup are they owned by any window?
Another thing that is very significant and I just remembered.
How do you create views? Is every view properly initialized and activated? Is every view added to a document’s views list?
