Constructor & Destructor Documentation

bgui_picker_tableau::bgui_picker_tableau ( vgui_tableau_sptr const & t )

Constructor, takes a child tableau.

Definition at line 24 of file bgui_picker_tableau.cxx.

bgui_picker_tableau::~bgui_picker_tableau ( )

Destructor.

Definition at line 49 of file bgui_picker_tableau.cxx.

Member Function Documentation

void bgui_picker_tableau::anchored_pick_point	(	const float	anch_x,
		const float	anch_y,
		float *	x,
		float *	y
	)

Gets a user selected polygon.

Gets a user selected point (x, y).

Pick a point with an anchored line indicator.

This function grabs the event loop and will not return until a mouse button down event occurs.

Definition at line 173 of file bgui_picker_tableau.cxx.

void bgui_picker_tableau::draw_anchor_line ( ) [private]

Draw a line to help the user pick it.

Definition at line 133 of file bgui_picker_tableau.cxx.

void bgui_picker_tableau::draw_box ( ) [private]

draw box.

Draw a box to help the user pick it.

Definition at line 114 of file bgui_picker_tableau.cxx.

void bgui_picker_tableau::draw_line ( ) [private]

Draw a line to help the user pick it.

Definition at line 99 of file bgui_picker_tableau.cxx.

bool bgui_picker_tableau::handle ( const vgui_event & e ) [virtual]

Handles all events for this tableau.

We grab events in this way rather than using a vgui_event_server because if we look at events outside the handle function then the gl state associated with those events will have changed. This means for a draw_overlay event we would end up drawing into the wrong buffer. For a mouse event we would not be able to get the position in the image using the projection_inspector (if e.g. the image was zoomed) since all the gl matrices would have been reset.

Reimplemented from vgui_tableau.

Definition at line 268 of file bgui_picker_tableau.cxx.

bool bgui_picker_tableau::next ( ) [private]

Get next event in the event loop.

Get next event in event loop.

Definition at line 483 of file bgui_picker_tableau.cxx.

void bgui_picker_tableau::pick_box	(	float *	x1,
		float *	y1,
		float *	x2,
		float *	y2
	)

Gets a user selected box specified by corner points).

Definition at line 76 of file bgui_picker_tableau.cxx.

void bgui_picker_tableau::pick_line	(	float *	x1,
		float *	y1,
		float *	x2,
		float *	y2
	)

Gets a user selected line.

This function grabs the event loop and will not return until two mouse down events occur. The parameters return the two points defining the line.

Definition at line 148 of file bgui_picker_tableau.cxx.

bool bgui_picker_tableau::pick_point	(	float *	x,
		float *	y
	)

Gets a user selected point.

This function grabs the event loop and will not return until a mouse down event occurs. Returns true if this is done with the left mouse button, otherwise false. The coordinates of the point are returned in the parameters.
