Macros

#define wxDECLARE_APP(className)
 This is used in headers to create a forward declaration of the wxGetApp() function implemented by wxIMPLEMENT_APP(). More...
 
#define wxIMPLEMENT_APP(className)
 This macro defines the application entry point and tells wxWidgets which application class should be used. More...
 
#define wxIMPLEMENT_APP_CONSOLE(className)
 This macro defines the application entry point for non-GUI applications and tells wxWidgets which application class should be used. More...
 
#define wxIMPLEMENT_WXWIN_MAIN
 This macro defines the application entry point appropriate for the current platform. More...
 
#define wxIMPLEMENT_WXWIN_MAIN_CONSOLE
 This macro defines the application entry point for console applications. More...
 
#define wxDISABLE_DEBUG_SUPPORT()
 Use this macro to disable all debugging code in release build when not using wxIMPLEMENT_APP(). More...
 

Functions

wxAppDerivedClass & wxGetApp ()
 This function doesn't exist in wxWidgets but it is created by using the wxIMPLEMENT_APP() macro. More...
 
bool wxHandleFatalExceptions (bool doIt=true)
 If doIt is true, the fatal exceptions (also known as general protection faults under Windows or segmentation violations in the Unix world) will be caught and passed to wxApp::OnFatalException. More...
 
bool wxInitialize ()
 This function is used in wxBase only and only if you don't create wxApp object at all. More...
 
void wxUninitialize ()
 This function is for use in console (wxBase) programs only. More...
 
void wxWakeUpIdle ()
 This function wakes up the (internal and platform dependent) idle system, i.e. More...
 
bool wxYield ()
 Calls wxAppConsole::Yield if there is an existing application object. More...
 
bool wxSafeYield (wxWindow *win=NULL, bool onlyIfNeeded=false)
 Calls wxApp::SafeYield. More...
 
int wxEntry (int &argc, wxChar **argv)
 This function initializes wxWidgets in a platform-dependent way. More...
 
int wxEntry (HINSTANCE hInstance, HINSTANCE hPrevInstance=NULL, char *pCmdLine=NULL, int nCmdShow=SW_SHOWNORMAL)
 See wxEntry(int&,wxChar**) for more info about this function. More...
