DTK_DRAW_SHAPE(3) Draw Toolkit manual DTK_DRAW_SHAPE(3)NAME
dtk_draw_shape - Draw a shape in the window
SYNOPSIS
#include <drawtk.h>
void dtk_draw_shape(const dtk_hshape shp);
DESCRIPTION
dtk_draw_shape() draw the shape referenced by shp in the current window. The position of the drawing depends on the rotation and transla-
tion previously set by dtk_*move_shape() and dtk_*rotate_shape() (the rotation is first applied to the shape and then the translation).
This function assumes there is a valid OpenGL rendering context in the calling thread. So a successfull call to dtk_make_current_window()
should have been performed previously in the current thread.
RETURN VALUE
None.

DTK_CREATE_COMPOSITE_SHAPE(3) Draw Toolkit manual DTK_CREATE_COMPOSITE_SHAPE(3)NAME
dtk_create_composite_shape - Create or modify a shape holding other shapes
SYNOPSIS
#include <drawtk.h>
dtk_hshape dtk_create_composite_shape(dtk_hshape shp,
unsigned int num,
const dtk_hshape *list,
int free_children);
DESCRIPTION
dtk_create_composite_shape() creates a shape made of num different shapes specified by the array list. When dtk_draw_shape(3) is called on
the composite shape, all referenced shapes will be rendered in the order of list. The composite shape create its own copy of the shape
list, so there is no need to keep the array pointed by list allocated after the function returns.
If free_children is a non-zero value, the destruction of the composite shape will destroy the underlaying shapes. If free_children is zero,
destroying the composite shape will leave the referenced shapes untouched, so that dtk_destroy_shape() should be called for all individual
shapes.
shp can be used to modify a previously created shape. If it is non-null, the handle will be used to modify the shape referenced by shp: no
new shape is created and the returned value is ensured to be shp in case of success, NULL otherwise. If shp is NULL, the function will
attempt to create a new shape.
RETURN VALUE
In case of success the function returns the handle to the newly created or modified shape. If the shp argument is non-null, the handle
returned is the same value. In case of error, NULL is returned.
