I have several controls, all which can pop up a context menu. I have the event table setup to produce wxCommandEvent objects via the EVT_MENU macro. In the EVT_MENU handler, how can I tell which control initiated the event? I see it's possible to get the id of the menu item, but I see nothing to get...

Ah, yes. I was making the mistake of trying to handle the event in the parent. I moved the handler to a subclass of wxRichTextCtrl and it's working great!

Thanks.

Is there a way to be notified when a wxRichTextCtrl loses focus?

Nothing is documented for this, and looking through the code I didn't see any mechanism for notification. (Not sure why this was omitted.) I tried putting an EVT_KILL_FOCUS handler in just be sure. No luck.

Thanks.

You are so right, Auria. I wrote a two frame app and I can close either window independently, and the app terminates only after the second one closes. Perfect.

Now comes the fun part

I haven't tried a small test app yet. Give me some time and I'll let you know.

I forgot to mention that I am creating the frames with NULL for the parent - if I didn't then the original parent will always be behind the new ones. I'll add that this wx behavior makes some sense: most apps have just one frame and the app needs to know when to shut down - the implementation assume...

My app creates a number of wxFrame windows - essentially like an SDI app. The problem occurs when the user closes one of the window - all windows end up getting destroyed. I want only the subject window to close. More specifically, in the EVT_CLOSE handler for the wxFrame, I'm calling Destroy. This ...

This is great info. Thanks! Don't know how I missed it.

Does wxWidgets provide any api for getting native settings? I've looked but haven't found anything. I'm making a custom control - more or less - and would like it to have a native look and feel. That is, it should use background and foreground colors typical for other controls, simlilarly for fonts,...

I see this is an old thread, but hopefully still relevant. Similar to rgruian, I was looking into disabling scrollbars and also having the control size itself vertically to exactly fit its contents. The first part turns out to be really easy - just override SetupScrollbars like this: void SetupScrol...

Thanks to both of you! I had originally thought that OnSize and the other GUI callbacks were single threaded but it was appearing that, maybe, they were not. Anyway, with your affirmation, I quickly went back looking for the culprit. Found it: a calls to wxSize size = GetBestVirtualSize(); SetVirtua...

This ought to be simple... I have an OnSize function for a wxScrolledWindow. Sometimes it takes a long time to executes and I discovered it was being reentered before finishing. So, I tried adding a wxMutex in it, as follows. But, it's not blocking on the Lock. class Pane : wxScrolledWindow { ... vo...

First, I like the idea from the UI point of view - less user interruption by annoying OK, Cancel buttons. I'm doing the same thing, more or less, so will be interested to see what defficienies you run into. Your case is a little different than mine in that I think you are saving a group of fields wh...

I guess I'm missing your point. Certainly, within a window, if you tab from control to control, the window should scroll to keep the focus in view. However, I can't imagine why a popup dialog should cause the underlying window to scroll without some app-level code to do so. Try my code and you'll se...

Just tried you suggestion - overriding wxChildFocusEvent. It works! So, thanks for coming up with this workaround.

It still seems like a bug in wxDialog, though. What do you think?
