wxPanel

A panel is a window on which controls are placed. It is usually placed within a frame. It contains minimal extra functionality over and above its parent class wxWindow; its main purpose is to be similar in appearance and functionality to a dialog, but with the flexibility of having any window as a parent.

Note: if not all characters are being intercepted by your OnKeyDown or OnChar handler, it may be because you are using the wxTAB_TRAVERSAL style, which grabs some keypresses for use by child controls.

wxPanel::wxPanel



wxPanel(void)

Default constructor.



wxPanel(wxWindow* parent, wxWindowID id = $-1$, const wxPoint& pos = wxDefaultPosition, const wxSize& size = wxDefaultSize, long style = wxTAB_TRAVERSAL, const wxString& name = ``panel")

Constructor.

Parameters

parent
The parent window.

id
An identifier for the panel. A value of -1 is taken to mean a default.

pos
The panel position. A value of (-1, -1) indicates a default position, chosen by either the windowing system or wxWidgets, depending on platform.

size
The panel size. A value of (-1, -1) indicates a default size, chosen by either the windowing system or wxWidgets, depending on platform.

style
The window style. See wxPanel.

name
Used to associate a name with the window, allowing the application user to set Motif resource values for individual dialog boxes.

wxPanel::Create



wxPanel::~wxPanel



~wxPanel(void)

Destructor. Deletes any child windows before deleting the physical window.



wxPanel::Create



bool Create(wxWindow* parent, wxWindowID id, const wxPoint& pos = wxDefaultPosition, const wxSize& size = wxDefaultSize, long style = wxTAB_TRAVERSAL, const wxString& name = ``panel")

Used for two-step panel construction. See wxPanel::wxPanel for details.



wxPanel::GetDefaultItem

wxWindow* GetDefaultItem(void) const

Returns a pointer to the button which is the default for this window, or NULL. The default button is the one activated by pressing the Enter key.



wxPanel::InitDialog



void InitDialog(void)

Sends a wxInitDialogEvent, which in turn transfers data to the dialog via validators.

wxInitDialogEvent



wxPanel::OnSysColourChanged



void OnSysColourChanged(wxSysColourChangedEvent& event)

The default handler for wxEVT_SYS_COLOUR_CHANGED.

Parameters

event
The colour change event.

Remarks

Changes the panel's colour to conform to the current settings (Windows only). Add an event table entry for your panel class if you wish the behaviour to be different (such as keeping a user-defined background colour). If you do override this function, call wxEvent::Skip to propagate the notification to child windows and controls.

wxSysColourChangedEvent



wxPanel::SetDefaultItem



void SetDefaultItem(wxButton *btn)

Changes the default button for the panel.

GetDefaultItem



wxPanel::SetFocus



virtual void SetFocus(void)

Overrides wxWindow::SetFocus. This method uses the (undocumented) mix-in class wxControlContainer which manages the focus and TAB logic for controls which usually have child controls. In practice, if you call this method and the control has at least one child window, the focus will be given to the child window.

See also

wxFocusEvent wxWindow::SetFocus



wxPanel::SetFocusIgnoringChildren



virtual void SetFocusIgnoringChildren(void)

In contrast to wxPanel::SetFocus (see above) this will set the focus to the panel even of there are child windows in the panel. This is only rarely needed.

wxFocusEvent wxPanel::SetFocus
