Field Documentation

view_t** children

The child views.

void* data

User supplied data.

Purely for external use. The view functions do not touch this at all except view_new(), which just sets it to 0.

void(* draw)(view_t *view)

Callback for drawing the view.

defaults to view_draw(). if overridden, the supplied callback should call view_draw() to draw any child views unless the view is a leaf view.

Note

All coordinates are set appropriately before this is called.

Parameters

view	This view.

grav_t gravity

The gravity of the view.

int max_children

Size of children array.

int num_children

Number of child views in view.

view_t* parent

The parent view.

unsigned resize_x

If true, view's width follows parent's.

unsigned resize_y

If true, view's height follows parent's.

void(* setgeometry)(view_t *view)

Callback for when the position and/or size of the view changes.

Set this if the underlying drawing system needs to take any action when the view's geometry changes (eg, moving/resizing the window in curses).

Note

All coordinates are set appropriately before this is called.

Parameters

view	This view.

unsigned visible

If false, view_draw() skips this view.

int xabs

Absolute coordinates of the top left (northwest) corner of the view.

Set interally.

int xlen

Size of the view.

int xpos

Coordinates of view's origin relative to parent's gravity point.

int xrel

Coordinates of the top left (northwest) corner of the view relative to the parent view's top left corner.

Set internally.

int yabs

int ylen

int ypos

int yrel
