I don't know how you do in wxDevCpp 6.10, but I guess you can search the file shellapi.h on your system and look whether it has definition for NIIF_INFO or not, if not, then download the latest platform SDK from microsoft and update your adv project by adding a preprocessor _WIN32_IE=0x600 and then recompile the adv project. You can use the free Microsoft Visual Studio 2005 Express for that.

EVT_TASKBAR_BALLOON_CLICK will be triggered when the user clicks on the balloon
How does ShowBallon works? I use the following code in my OnInit. But no balloon is shown.

Code: Select all

	taskbar.SetIcon(wxICON(amain),_T("This is a testing"));	
	taskbar.ShowBalloon(_T("This is a test"),_T("This is a testing message"),10000,NIIF_INFO);

Any idea?

hi..
I have some errors with NOTIFYICONDATA struct.
I've tried anything but the problem is still there.
I'm using wxDev-c++ 6.10.2 with minGW 3.4.5
when i'm trying to create a balloontip in the compilation it says me:

Code: Select all

In function `WindowProcedure': 
structure has no member named `uTimeout' 
structure has no member named `szInfoTitle'
structure has no member named `szInfo'
the i've tried to write this to the resource file

Code: Select all

define _WIN32_IE 0x0501
but its still don'w work.. and now i have some conflict in definition of _WIN32_IE cause i need to write in the source file this

Code: Select all

#ifndef _WIN32_IE
#define _WIN32_IE 0x0300
#endif
cause if i don't it says me [Warning] implicit declaration of function `InitCommonControlsEx'

when i write just define _WIN32_IE 0x0501 and delete the _WIN32_IE 0x0300 the program compiles good without errors but the balloontip doesn't work anyway..

how to fix this ?
thanks..

I used the information here to adopt my code to generate ballon tooltips by my application. This worked perfect until wxwidgets version 2.8.6!

Unfortunately, my code stoped working when going to wxwidgets 2.8.8. The behavior when entering the ballon routine is as follows: The system tray adds an 'empty' icon field and the ballon tooltip is NOT shown (formerly it was). After the timeout the empty field is removed.

Here is the code which stopped working after 2.8.6:

Code: Select all

bool TaskBarIcon::ShowBalloonTip(wxString title, wxString message, unsigned int timeout, int icon)
{
	NOTIFYICONDATA 	notifyData;
	wxIcon			tool_icon(tool_xpm);

	memset(&notifyData, 0, sizeof(NOTIFYICONDATA));
	notifyData.cbSize = sizeof(NOTIFYICONDATA);
  	notifyData.uFlags = NIF_INFO | NIF_MESSAGE;
	notifyData.hWnd = (HWND) parent->GetHWND();
	notifyData.uID = 99;
  	notifyData.uTimeout = timeout;
  	notifyData.hIcon = (HICON) tool_icon.GetHICON();
	notifyData.dwInfoFlags = icon | NIIF_NOSOUND | NIIF_INFO;

	wxStrncpy(notifyData.szInfo, message.c_str(), WXSIZEOF(notifyData.szInfo));
	wxStrncpy(notifyData.szInfoTitle, title.c_str(), WXSIZEOF(notifyData.szInfoTitle));

	Shell_NotifyIcon(NIM_ADD, &notifyData);

	wxSleep((int) (timeout / 100.0));

	return (Shell_NotifyIcon(NIM_DELETE, &notifyData) != 0);
}
Could anyone please guide me why this is not working anymore? Were there changes regarding this in wxwidgets releases after 2.8.6?

My platform is Windows XP (SP3) and MinGW/gcc.

Edit (2008-07-29): I've modified the taskbar sample which comes with wxwidgets (./samples/taskbar) and included the above function. The code compiled with the corresponding makefile and wxwidgets 2.8.4 works, the balloon tooltip is shown. The same code compiled with 2.8.8 doesnt work.

Thanks,
Stefan.

I've tested your binaries :
- the 2.8.4 version works (i mean balloon tips work)
- the 2.8.8 does not work

Meanwhile I found out what's wrong. The misbehaviour only appears with MinGW 3.4.5 and thus is independent of the wxWidgets version.

The balloon tooltip behaviour depends on the definitions of the NOTIFYICONDATA struct in shellapi.h.

I think wxPopup is better than it.

I have created a replacement wxTaskBarIcon class (wxTaskBarIconEx) that has support for balloon tips and enhanced functionality found in newer versions of Windows (large icons for e.g.). Due to time, I have yet to attempt to merge any of wxWidgets as a complete replacement. The class works on 2k+.

Hopefully this can be useful to someone and/or can be built upon.
