wxWidgets Discussion Forum

What I wanted to know is how wxWidgets does the detection internally. The code is in the file i mentioned above. Here it is: static wxString GetSM() { wxX11Display dpy; if ( !dpy ) return wxEmptyString; char smerr[256]; char *client_id; SmcConn smc_conn = SmcOpenConnection(NULL, NULL, 999, 999, 0 /...

when I click one row, tab key not work too...

Does it work in the "listctrl" sample? What do you expect to happen when you press TAB inside the listctrl?

How do you catch the events? Mouse events don't propagate to parent controls, so you have to catch them at the object itself. That means you either have to derive your own class from wxStaticBitmap or you have to use Connect(). An entry in the event table macro of the wxFrame won't work.

Ok, i tested this now. The problem is that a wxGauge doesn't get focus when you click it. And mouse wheel events always go to the control that has focus. I works if you catch the mouse click event on the wxGauge and in its event handler you call SetFocus(). But i'm still not sure that it's a good id...

Which platform and wxWidgets version?

Do you have a wxPanel as parent for the wxListCtrl? If not, do that.

Your question is not clear. If you only want one control, why to you create two?
Why don't you call DragAcceptFiles() on the wxRichTextCtrl?

You should check the "dnd" sample that comes with wxWidges. Also, read the textfile "d_and_d.txt" in <wx>/samples/dnd/

Your question is not clear.

Do you want to know how to use wxAppTraits::GetDesktopEnvironment? Or do you want to know how wxWidgets does the detection internally?
Check method GetSM() in <wx>/src/gtk/utilsgtk.cpp

I haven't tested it myself, but the docs for wxGauge say:

Event handling
wxGauge is read-only so generates no events.

If you want to use it as a control, you probably have to write your own custom control. Which shouldn't be so hard as drawing a gauge is pretty simple.

It's implemented for MSW and OSX, but not GTK.

But it's the best wxWidgets can do for you.

Does that mean you already tried and it didn't work? If yes, please show the code how you did it.

You mean you want to receive the keyboard shortcut even if your application is not active?

Otherwise, for "normal" keyboard shortcuts:

Using either wxHtmlWindow or wxWebView for just displaying a very simple bit of static text seems like massive overkill. But it doesn't cost you anything. And if it does the job, who cares? Besides, it seems like the desired behavior is the right behavior anyway - I think there are bugs here. I ten...

I remember someone else having that problem, but i can't find the post any more.

Check this modified "minimal" sample, it should give you a push in the right direction. Beware that it requires a few "hacks", so i'm not sure if it works on all platform. I only tested under MSW.

I copied this in the "minimal" sample, at the end of the MyFrame ctor: wxScrolledWindow *scrol = new wxScrolledWindow(this, wxID_ANY); scrol->SetScrollRate(10,10); wxSizer *sizer = new wxBoxSizer(wxVERTICAL); for(int i=0; i<40; i++) { wxString label; label << "button " << i; wxBu...

Just replace wxPanel with wxScrolledWindow and it should work.
