Inheritance diagram for wxAuiTabArt:

Detailed Description

Tab art provider defines all the drawing functions used by wxAuiNotebook.

This allows the wxAuiNotebook to have a pluggable look-and-feel.

By default, a wxAuiNotebook uses an instance of class wxAuiDefaultTabArt, derived from this class, which provides bitmaps and a colour scheme that is adapted to the major platforms' look. You can either derive from that class to alter its behaviour or write a completely new tab art class.

Another example of creating a new wxAuiNotebook tab bar is wxAuiSimpleTabArt.

Call wxAuiNotebook::SetArtProvider() to make use of this new tab art.

Constructor & Destructor Documentation

◆ wxAuiTabArt()

wxAuiTabArt::wxAuiTabArt ( )

Constructor.

Member Function Documentation

◆ Clone()

virtual wxAuiTabArt* wxAuiTabArt::Clone ( )

pure virtual

Clones the art object.

Implemented in wxAuiSimpleTabArt, and wxAuiGenericTabArt.

◆ DrawBackground()

virtual void wxAuiTabArt::DrawBackground	(	wxDC &	dc,
		wxWindow *	wnd,
		const wxRect &	rect
	)

pure virtual

Draws a background on the given area.

Implemented in wxAuiSimpleTabArt, and wxAuiGenericTabArt.

◆ DrawButton()

virtual void wxAuiTabArt::DrawButton	(	wxDC &	dc,
		wxWindow *	wnd,
		const wxRect &	in_rect,
		int	bitmap_id,
		int	button_state,
		int	orientation,
		wxRect *	out_rect
	)

pure virtual

Draws a button.

Implemented in wxAuiSimpleTabArt, and wxAuiGenericTabArt.

◆ DrawPageTab()

virtual int wxAuiTabArt::DrawPageTab	(	wxDC &	dc,
		wxWindow *	wnd,
		wxAuiNotebookPage &	page,
		const wxRect &	rect
	)

virtual

Draws a tab for the specified notebook page.

This function must be overridden if DrawTab() is not overridden and, also, if pinned tabs are used, as they are not supported by DrawTab().

The pane contains the information about the page to draw, in particular its wxAuiNotebookPage::buttons specifies the buttons to draw if it is not empty and receives the rectangles where they were drawn on output in the wxAuiTabContainerButton::rect fields.

Note that if a button state is wxAUI_BUTTON_STATE_HIDDEN, the effect is the same as not including this button at all, i.e. it is not drawn and the output field is not modified in this case.

The wxAuiNotebookPage::rect field is also updated by this function to contain the bounding rectangle of the tab.

Returns: The total horizontal span of the tab, which may be greater than the page bounding rectangle.

Since: 3.3.0

◆ DrawTab()

virtual void wxAuiTabArt::DrawTab	(	wxDC &	dc,
		wxWindow *	wnd,
		const wxAuiNotebookPage &	page,
		const wxRect &	rect,
		int	close_button_state,
		wxRect *	out_tab_rect,
		wxRect *	out_button_rect,
		int *	x_extent
	)

virtual

Draws a tab.

This function used to be pure virtual and so had to be overridden in the derived classes in the previous versions of wxWidgets, however since version 3.3.0 it doesn't have to be overridden if DrawPageTab() is overridden and, moreover, it is recommended to override DrawPageTab() instead of this function in the new code.

Reimplemented in wxAuiSimpleTabArt, and wxAuiGenericTabArt.

◆ GetBestTabCtrlSize()

virtual int wxAuiTabArt::GetBestTabCtrlSize	(	wxWindow *	,
		const wxAuiNotebookPageArray &	,
		const wxSize &
	)

pure virtual

Returns the tab control size.

Implemented in wxAuiSimpleTabArt, and wxAuiGenericTabArt.

◆ GetButtonRect()

virtual int wxAuiTabArt::GetButtonRect	(	wxReadOnlyDC &	dc,
		wxWindow *	wnd,
		const wxRect &	inRect,
		int	bitmapId,
		int	buttonState,
		int	orientation,
		wxRect *	outRect = `nullptr`
	)

virtual

Returns the rectangle for the given button.

This function is not pure virtual because it is only for multi-line tabs, but it must be implemented if wxAUI_NB_MULTILINE is used.

If specified, the returned rectangle must be filled with the same value as DrawButton() puts into its outRect but here it can also be null in which case just its width is returned.

Since: 3.3.0

◆ GetIndentSize()

virtual int wxAuiTabArt::GetIndentSize ( )

pure virtual

Returns the indent size.

Implemented in wxAuiSimpleTabArt, and wxAuiGenericTabArt.

◆ GetNormalFont()

virtual wxFont wxAuiTabArt::GetNormalFont ( ) const

virtual

Returns the font to use for normal, non-selected, tabs.

By default, returns an invalid font, meaning that the font set for wxAuiNotebook itself should be used.

This function should be overridden for SetNormalFont() to actually work.

Since: 3.3.0

◆ GetPageTabSize()

virtual wxSize wxAuiTabArt::GetPageTabSize	(	wxReadOnlyDC &	dc,
		wxWindow *	wnd,
		const wxAuiNotebookPage &	page,
		int *	xExtent = `nullptr`
	)

virtual

Returns the size of the tab for the specified notebook page.

This function must be overridden if GetTabSize() is not overridden and, also, if pinned tabs are used, as they are not supported by GetTabSize().

Since: 3.3.0

◆ GetSelectedFont()

virtual wxFont wxAuiTabArt::GetSelectedFont ( ) const

virtual

Returns the font to use for the selected tab.

By default, returns an invalid font, meaning that the font set for wxAuiNotebook itself should be used.

This function should be overridden for SetSelectedFont() to actually work.

Since: 3.3.0

◆ GetTabSize()

virtual wxSize wxAuiTabArt::GetTabSize	(	wxReadOnlyDC &	dc,
		wxWindow *	wnd,
		const wxString &	caption,
		const wxBitmapBundle &	bitmap,
		bool	active,
		int	close_button_state,
		int *	x_extent
	)

virtual

Returns the tab size for the given caption, bitmap and state.

This function used to be pure virtual and so had to be overridden in the derived classes in the previous versions of wxWidgets, however since version 3.3.0 it doesn't have to be overridden if GetPageTabSize() is overridden and it is recommended to override GetPageTabSize() instead of this function in the new code.

Reimplemented in wxAuiGenericTabArt.
