hi @all guys
isn't there any way to use theese balloons under non-windows systems?

i'm new to wxwidgets, so i don't undestand if this is only windows-related...

tnx in advance :)

The wxWidgets toolkit does not (always) custom draw the elements. It simply wraps the native components making it a familiar environment no matter where you develop your code. Windows, Unix, Mac. The downside only parts that can be shared (like the set of components all OS'es have in common) are limited. Some people would however like to use Windows only things like the balloon tooltips, so they are kind of added.

I do agree there needs to be a better distinquishing between Windows/Mac/Linux only components, and the set all OS'es share, and it might be confusing.

OK guys this is the latest patch. This version allows for event handling to be done (took me half a day to solve the mystery of the undefined symbol :P)

Nice Lowjoel - Kudos!

As for it in a seperate class, well that is a good idea as well...

Digital Mars compiler has some problem with NOTIFYICONDATA....

Code: Select all

Any idea?

Cool, any chance of seeing a version for normal (non task bar icon) bubble tooltips?

steal don't get this

Post by mromanuk » Mon Apr 10, 2006 5:52 am

Hello, this is my first message here, I have been using wxWidgets for around 2 months now( I used it before for a while).

Ok, my problem is with this balloon tooltip and the systray. I have tried this code many times but I can't get it to work... I use to work with Linux (crosscompiling with mingw32 for win32) but now I am using a WinXP with devcpp 4.9.9.2 and wxWidgets 2.6.2, and I have the same problem:

As stated by [email protected] upper in this thread, when I do

notifyData.hWnd = (HWND) m_win->GetHWND();

I get this error:
627 C:\install\developer\wx\winsrc\Accounts.cpp invalid use of undefined type `struct wxTaskBarIconWindow'
23 C:\Dev-Cpp\include\wx\msw\taskbar.h forward declaration of `struct wxTaskBarIconWindow'


I don`t know how to fix this...Ok I hope anybody can help me,
Thanks in advance,
Martin

Hey guys,

sorry, have been VERY busy lately, and I probably wont be on the forum much anymore :(

Oldest to newest:
Trikko: define _WIN32_IE > 0x500 (0x600 is best - though 0x500 is the min)
KSmith: I have a working one at the moment, but I'm nt releasing it (yet). See http://joelsplace.sg/documents/files/pu ... -login.png
mromanuk: please provide some code to show me.

Best regards,
Joel

Guys, I've read the posts above and tried to get the ballon tips to work, and I just can't, get things to compile.

I get the following errors:

`sm_taskbarMsg' undeclared (first use this function)
'struct NOTIFYICONDATA' has no member named 'szInfo'

Does, anyone have a working example, I'm using wxDevCpp 6.10

Thanks...

You are sure that you set the makro definition -D_WIN32_IE=0x0500 when you compile the taskbar.cpp?

Then set _WIN32_IE to be 0x600, meh, the Windows SDK isn't clear sometimes...

Any working examples...?

Post by gbd » Sat Dec 16, 2006 10:09 am

Thanks for the ideas, I've tried both of the above, still no good.

Any change someone could give me a working example, with include statements of the relavent files...?

Thanks in advanced.
