My main dialog window contains a wxNotebook. The wxNotebook contains 3 panels, which of course can be navigated through by using the 3 tabs at the top of the notebook. My program works absolutely fine on Linux (wxGTK). However, I complied it on MS-Windows 7 Ultimate, ran it, but the wxNotebook doesn...

OK so I'm developing a multi-threaded application. There's two threads: ============================================================ Thread 1 : Main Thread : This is the main GUI thread. The main GUI thread displays a dialog box. On this dialog box, there is a wxListCtrl which displays information s...

If you create a local variable within a function, there's only 2 ways that the variable can be altered from outside of that function: 1) If you pass the variable's address to another function 2) If you pass the variable by reference to another function (It's possible that you could use a preprocesso...

I'm running the latest version of 32-Bit Ubuntu (Lucid Lynx). I installed Codeblocks and the wxWidgets development libraries in the most vanilla fashion possible by using "apt-get" as follows: apt-get install codeblocks apt-get install libwxgtk2.8-dev libwxgtk2.8-dbg I opened up Codeblocks, clicked ...

Create a wxListCtrl and set it to Report Mode (i.e. wxLC_REPORT). I have done some testing with wx2.8 under GTK, and it appears that the wxWidgets library segfaults if you add an item to the wxListCtrl before having added a column. Firstly, let me show you some code that works fine. You can copy thi...

I found a workaround for what I'm trying to achieve. I have a wxNoteBook, and it contains 3 wxPanel's. When a tab is clicked on, a new panel appears, and I want each panel to have its own default button. The wxNotebook class has a PAGE_CHANGED event, so I use it as follows: void DialogMain::OnTabCha...

If you look at the manual for wx2.6, you'll see that the wxPanel class contains a member function called SetDefaultItem: http://docs.wxwidgets.org/2.6/wx_wxpanel.html However, if you look at the manual for wx2.8, the function is no longer listed: http://docs.wxwidgets.org/2.8/wx_wxpanel.html I've se...

The following didn't work: m_static_status->SetLabel( wxT("one two three four five six seven") ); this->Layout(); However the following did work: m_static_status->SetLabel( wxT("one two three four five six seven") ); m_static_status->GetParent()->Layout(); The parent of my wxStaticText control is a ...

I like TrV's idea of simply hiding the main GUI.

That's what Firefox does if you close it while there's something currently downloading.

The wxSQLite3FunctionContext class might contain a pointer member variable as follows: class wxSQLite3FunctionContext { protected: void *p; }; This variable, "p", stores the memory address of some particular data. It looks as though wxSQLite3FunctionContext wants to give you the ability to change th...

I have a wxStaticText control centered in the middle of my main dialog box. When I run my program and manually resize the main dialog using the mouse, the wxStaticText control is automagically repositioned so that it remains in the middle of the dialog box. No problem there. OK so let's say that my ...

Thanks a lot for your reply. It actually wouldn't be impossible for me to do one of the following: a) Call an a synchronous function instead or b) Call a "semi-synchronous" function that is synchronous until it times out and returns. But I really don't want to do either of those because my code is s...

You might see some really bad programming errors in this post, but please humour me and read all the way to end before beginning to compose your reply. Let's say we have a thread that makes the PC speaker beep periodically (i.e. beep beep beep). This thread is extremely simple: class BeeperThread : ...

Here's what I have in the constructor of the main dialog box for my program: DialogMain::DialogMain( wxWindow* parent ) : DialogMainTemplate( parent ) { timer_refresh_sniffbox = new wxTimer(this); timer_refresh_sniffbox->Connect( wxEVT_TIMER, wxTimerEventHandler( DialogMain::OnTimerRefreshSniffBox )...

OK I got the answers I needed. It turns out that I don't need volatile. There's a short discussion of it here: http://groups.google.ie/group/comp.lang.c++/browse_thread/thread/4e68d5b929c344d4/ Also regarding the atomic thing with 32-Bit integers, well that's a no-no as well. I can't remember exactl...
