Detailed Description

Tableau where the user can set the projection and modelview matrices.

Class vgui_loader_tableau is a tableau which (optionally) loads given values for the projection and modelview matrices before passing control to its child. This is typically used to initialize GL before rendering a scene.

Constructor & Destructor Documentation

vgui_loader_tableau::vgui_loader_tableau ( vgui_tableau_sptr const & child )

Constructor - don't use this, use vgui_loader_tableau_new.

Takes the single child tableau as a parameter.

Definition at line 22 of file vgui_loader_tableau.cxx.

vgui_loader_tableau::~vgui_loader_tableau ( ) [inline, protected]

Destructor - called by vgui_loader_tableau_sptr.

Member Function Documentation

bool vgui_wrapper_tableau::add_child ( vgui_tableau_sptr const & c ) [virtual, inherited]

Adds given tableau as child if none exists, else causes error.

Reimplemented from vgui_tableau.

Definition at line 42 of file vgui_wrapper_tableau.cxx.

void vgui_tableau::add_popup ( vgui_menu & ) [virtual, inherited]

Add the given menu to the popup menu for the tableau.

Add given menu to the tableau popup menu.

This method is for tableaux to implement if they want to _add_ some items to the popup menu. They can assign to or clear 'menu', but that is not recommended as it would remove what other tableaux put there. The recommended usage is to .add() items or to .include() another menu.

** This is an interface method. it abstracts a behaviour. **

Reimplemented in vgui_satellite_tableau_t< object, data >, vgui_active_tableau, and vgui_clear_tableau.

bool vgui_loader_tableau::handle ( vgui_event const & e ) [protected, virtual]

It is pointless to derive from vgui_wrapper_tableau unless this method is also overridden!

Reimplemented from vgui_wrapper_tableau.

Definition at line 55 of file vgui_loader_tableau.cxx.

bool vgui_tableau::help ( ) [virtual, inherited]

Called by default handle when it receives a '?' pressed event.

		vgui_button	,
		vgui_modifier
	)		`[virtual, inherited]`

Called by default handle when it receives a mouse down event.

Reimplemented in vgui_listmanager2D_tableau, vgui_viewer2D_tableau, vgui_function_tableau, vgui_viewer3D_tableau, vgui_displaylist3D_tableau, and vgui_displaylist2D_tableau.

		vgui_tableau_sptr const &	new_child
	)		`[virtual, inherited]`

Called whenever a child of this tableau is about to be forcibly replaced.

Called when a child of this tableau is forcibly replaced.

This method is called when some part of the program (typically the parent_child_link mechanism) is about to forcibly replace a child of this tableau. The canonical reason to override this is in order to invalidate caches.

Definition at line 302 of file vgui_tableau.cxx.

void vgui_tableau::post_idle_request ( void ) [virtual, inherited]

Post an idle request event.

The fact that this is virtual does not imply that you should go and override it.

Posting an idle event request means that your tableau has some idle processing that it'd like to do. This means that your tableau will continue to receive vgui_IDLE events until the event handler returns false (i.e. all idle processing is complete). The idle event handler should return false when it has no idle processing, or has completed its idle processing. It may return true if has only partially completed its idle processing; in this case, it will receive more idle event to allow it to complete processing.

Reimplemented in vgui_adaptor_tableau.

Definition at line 235 of file vgui_tableau.cxx.

void vgui_tableau::post_message	(	char const *	msg,
		void const *	data
	)		`[virtual, inherited]`

Post a message event.

The fact that this is virtual does not imply that you should go and override it.

Reimplemented in vgui_adaptor_tableau.

Definition at line 205 of file vgui_tableau.cxx.

void vgui_tableau::post_overlay_redraw ( void ) [virtual, inherited]

Post an overlay-redraw event.

Post an overlay redraw event.

The fact that this is virtual does not imply that you should go and override it.

Reimplemented in vgui_adaptor_tableau.

Definition at line 225 of file vgui_tableau.cxx.

void vgui_tableau::post_redraw ( void ) [virtual, inherited]

Post a draw event.

The fact that this is virtual does not imply that you should go and override it.

Reimplemented in vgui_adaptor_tableau.

Definition at line 215 of file vgui_tableau.cxx.

vcl_string vgui_wrapper_tableau::pretty_name ( ) const [virtual, inherited]

Returns nice version of the name which also includes details of the child.

Reimplemented from vgui_tableau.

Definition at line 32 of file vgui_wrapper_tableau.cxx.

void vgui_tableau::ref ( ) const [inherited]

Increase the reference count by one (for smart pointers).

Increase the reference count by one (for smart-pointers).

"const" is for convenience, it is cast away internally.

Definition at line 79 of file vgui_tableau.cxx.

bool vgui_wrapper_tableau::remove_child ( vgui_tableau_sptr const & c ) [virtual, inherited]

The child tableau is removed if it is the same as the given tableau.

Reimplemented from vgui_tableau.

Definition at line 54 of file vgui_wrapper_tableau.cxx.

void vgui_loader_tableau::set_identity ( )

Set projection and modalview matrices to the identity matrix.

Calling this method is equivalent to calling set_projection(I) and set_modelview(I) with I an identity matrix.

		unsigned	h

void vgui_loader_tableau::set_ortho	(	float	x1,
		float	y1,
		float	x2,
		float	y2
	)

Set projection matrix to identity and modelview matrix using glOrtho().

These easy methods set the projection matrix to the identity and the modelview matrix using glOrtho(). In each case, the coordinates given are the desired coordinates of the viewport/render-volume corners. Eg. to view an image which is w-by-h, one might use l.set_ortho(0,h, w,0); unless one wants the image upside down.
