Close generates a wxCloseEvent whose handler usually tries to close the window. ClientToScreen and ScreenToClient convert between coordinates relative to the top-left corner of this window, and coordinates relative to the top-left corner of the screen.

ClearBackground clears the window by filling it with the current background color. Centre ( Center), CentreOnParent ( CenterOnParent), and CentreOnScreen ( CenterOnScreen) center the window relative to the screen or the parent window. Use the static function GetCapture to retrieve the window with the current capture (if it's within the current application), and HasCapture to determine if this window is capturing input. This is useful in a drawing program, for example, so that moving to the edge of the canvas scrolls it rather than causing another window to be activated. CaptureMouse captures all mouse input, and ReleaseMouse releases the capture.

Browsing them should give you a good idea of the general capabilities of windows, and you can refer to the reference manual for details of parameters and usage. We can't describe them all here in detail, so instead we present a summary of some of the most important functions. WxWindow Member Functions Because wxWindow is the base class for all other window classes, it has the largest number of member functions.
#Wxwindow findfocus example update#
Processes a w圎VT_UPDATE_UI event, generated in idle time to give the window a chance to update itself. Processes a w圎VT_IDLE event, generated in idle time. Handlers take a wxSysColourChangedEvent object. Processes a w圎VT_SYS_COLOUR_ CHANGED event, generated when the user changed a color in the control panel (Windows only). Processes w圎VT_SET_FOCUS and w圎VT_KILL_ FOCUS events, generated when the keyboard focus is gained or lost for this window. Processes a w圎VT_SIZE event, generated when the window is resized. Processes a w圎VT_MOVE event, generated when the window moves.

Processes a w圎VT_ERASE_BACKGROUND event, generated when the window background needs updating. Processes a w圎VT_PAINT event, generated when the window needs updating. Handlers take a wxWindowDestroyEvent object. Processes a w圎VT_DELETE propagating event, generated when the window is about to be destroyed. Handlers take a wxWindowCreateEvent object. Processes a w圎VT_CREATE propagating event, generated when the underlying window has just been created. wxWindow Events wxWindow and all its derived classes generate the events listed in Chapter 6. For one-step construction, you use this constructor: wxWindow(wxWindow* parent, wxWindowID id, const wxPoint& pos = wxDefaultPosition, const wxSize& size = wxDefaultSize, long style = 0, const wxString& name = wxT("panel")) For example: wxWindow* win = new wxWindow(parent, wxID_ANY, wxPoint(100, 100), wxSize(200, 200)) wxWindow Styles Each window class may add to the basic styles defined for wxWindow, listed in Chapter 9 for more information on UI update events. As we've seen, a wxWindow may be created either in one step, using a non-default constructor, or two steps, using the default constructor followed by Create. However, it's more likely that you will derive classes from it (or use pre-existing derived classes) than use it on its own.

wxWindow wxWindow is both an important base class and a concrete window class that you can instantiate.

Use the API reference for these (and other) base classes as well as the reference for the derived classes to get a full understanding of what's available. It's worth mentioning base classes that you may or may not be able use directly but that implement a lot of functionality for derived classes.
