- @page roughguide_overview Writing a wxWidgets application: a rough guide
-
- To set a wxWidgets application going, you will need to derive a #wxApp class and
- override wxApp::OnInit.
- An application must have a top-level #wxFrame or #wxDialog window.
- Each frame may contain one or more instances of classes such as #wxPanel, #wxSplitterWindow
- or other windows and controls.
- A frame can have a #wxMenuBar, a #wxToolBar, a status line, and a #wxIcon for
- when the frame is iconized.
- A #wxPanel is used to place controls (classes derived from #wxControl)
- which are used for user interaction. Examples of controls are #wxButton,
- #wxCheckBox, #wxChoice, #wxListBox,
- #wxRadioBox, #wxSlider.
- Instances of #wxDialog can also be used for controls and they have
- the advantage of not requiring a separate frame.
- Instead of creating a dialog box and populating it with items, it is possible to choose
- one of the convenient common dialog classes, such as #wxMessageDialog
- and #wxFileDialog.
- You never draw directly onto a window - you use a @e device context (DC). #wxDC is
- the base for #wxClientDC, #wxPaintDC, #wxMemoryDC, #wxPostScriptDC,
- #wxMemoryDC, #wxMetafileDC and #wxPrinterDC.
- If your drawing functions have @b wxDC as a parameter, you can pass any of these DCs
- to the function, and thus use the same code to draw to several different devices.
- You can draw using the member functions of @b wxDC, such as wxDC::DrawLine
- and wxDC::DrawText. Control colour on a window (#wxColour) with
- brushes (#wxBrush) and pens (#wxPen).
- To intercept events, you add a DECLARE_EVENT_TABLE macro to the window class declaration,
- and put a BEGIN_EVENT_TABLE ... END_EVENT_TABLE block in the implementation file. Between these
- macros, you add event macros which map the event (such as a mouse click) to a member function.
- These might override predefined event handlers such as for #wxKeyEvent and
- #wxMouseEvent.
- Most modern applications will have an on-line, hypertext help system; for this, you
- need wxHelp and the #wxHelpController class to control
- wxHelp.
- GUI applications aren't all graphical wizardry. List and hash table needs are
- catered for by #wxList and #wxHashMap.
- You will undoubtedly need some platform-independent @ref filefunctions_overview,
- and you may find it handy to maintain and search a list of paths using #wxPathList.
- There's a #miscellany of operating system and other functions.
- See also @ref classesbycat_overview for a list of classes.
