Ok. I found the relevant code in "richtextbuffer.cpp:5275". It seems that you cannot change it. It just takes the color from the system's style. I'll probably edit the code to allow the optional definition of a different color. Do you think such a change would be accepted in the official distributio...

wxRichTextCtrl: Changing the selection color (style)

Hello,

Is there a way to change the selection (wxRichTextCtrl::SetSelection) color or style of a wxrichtextctrl (e.g. to something different than the default blue)?

Thank you,
Giannis

I don't mean to translate my whole application, I mean to translate the Cancel and Help button. But how do I do that? I already looked into that internat sample, but the Cancel button wasnt translated. If you want to change *all* the buttons then the only way to do it is to follow the i18n process ...

Hi,

You can use the "signal" function to catch the abnormal termination of your application.

Check the documentation at:

Note that the signal function is also available on Unix systems ... so this method is portable.

Regards,

Hi, Check the internationalization sample in your wx distribution: http://www.wxwidgets.org/manuals/2.6.3/wx_samples.html#sampleinternat Also, I recommend using poEdit (http://www.poedit.org/) for the translation of your application. Lastly, be sure to copy the corresponding "po" (is it da.po) file ...

In addition to the above suggestions,

If you want to do a somewhat "fuzzy" matching of the images and be able to discover similar or the same images even if they have different sizes you can calculate and compare their color histograms:

I found that I had to add the line delete wxConfigBase::Set((wxConfigBase *) NULL); before creating the new wxFileConfig. This deletes any existing config, which otherwise will be used whether you want it to or not. Why should there already be one? I'm guessing, but I suspect it's to do with the st...

Hmm... Now I noticed that you run the wxwidgets loop on a "secondary" thread ... Could you try running wxwidgets loop on the "main" thread and your engine on the other ??? I think wxwidgets is meant to run on the main thread. Also check: http://www.wxwidgets.org/manuals/2.6.3/wx_threadfunctions.htm ...

Have you cleaned up wxwidgets before exiting ?

Code: Select all

wxTheApp->OnExit();
wxApp::CleanUp();

this method is obviously gone. But you can pass all parameters to the ctor, you don't need the three additional calls. Yeah ... but obviously the guy creates the object once (when first needed) and then sets its parameters according to the arguments of the enclosing function. He probably doesn't wa...

Are there any hidden platform-dependencies I've introduced in this code? Your code is fine! Using a wxString as a storage buffer as I suggested above would be easier and you wouldn't have to explicitly manage heap storage. However your implementation is correct in the context you want to use it. A ...
