Idea behind return codes in wxMessageBox?
|
| |
Does anyone know what the idea is behind the wxMessageBox function returning codes like wxYES /wxNO / wxCANCEL instead of wxID_YES / wxID_NO / wxID_CANCEL? This makes it harder to use if you use it in combination with another dialog box (say, one where you ask if the user wants to save) and use a global variable for both return values. Since... more »

wxFileDialog limitations
|
| |
Hi, I ran into problems when trying to select *many* files at once with wxFileDialog. I'm using version 2.8.9 on 32bit windows. The 'File name:' input field is limited to a length of 2^15 characters. Is it possible to change this? I had a look at the source but it seems none of it is actually used because wxUSE_FILEDLG isn't set.... more »

wx-users mailing list and this newsgroup
|
| |
Since wx-users was moved to Google Groups, it looks like this newsgroup has become obsolete, as there's no longer a gateway between the mailing list and the newsgroup. I recommend that readers of this group migrate to this Gmane newsgroup: Server: news.gmane.org Newsgroup: gmane.comp.lib.wxwindows.gener al... more »

wxWidgets and exception safety, i.e. std::bad_alloc
|
| |
I'm wondering, how wxWidgets treats exception safety. The last discussion I found about it is quite old, so I think it's worth to reopen the subject. For example: ...wxFrame* f = ...; wxMenuBar* menuBar = new wxMenuBar; wxMenu* menu = new wxMenu; menu->Append( ID_1, _("Item1") ); funCall(); menuBar->Append( menu, _("&Menu1") );... more »

3.0, wxString, and STL algorithms
|
| |
Hi, Since wxString (in wxWidgets 3.0) is based on std::basic_string, can I use stl algorithms on wxString? For example, I'd like to use copy_backward() on a wxString. Gerald
