create_toolbar()

static fbtk_widget_t * create_toolbar ( struct gui_window *  gw, int  toolbar_height, int  padding, colour  frame_col, const char *  toolbar_layout  )

static

Create a toolbar window and populate it with buttons.

The toolbar layout uses a character to define buttons type and position: b - back l - local history f - forward s - stop r - refresh u - url bar expands to fit remaining space t - throbber/activity indicator c - close the current window

The default layout is "blfsrut" there should be no more than a single url bar entry or behaviour will be undefined.

Parameters

gw	Parent window
toolbar_height	The height in pixels of the toolbar
padding	The padding in pixels round each element of the toolbar
frame_col	Frame colour.
toolbar_layout	A string defining which buttons and controls should be added to the toolbar. May be empty string to disable the bar..
