- begin_
complex_ polygon - Starts drawing a complex filled polygon
- begin_

fl_vertex() - begin_
polygon - Starts drawing a convex filled polygon

- draw_
frame2 - Draws a series of line segments around the given box
- draw_
image - Draw an image into a widget.
Requires a call to
app::set_visual(Mode::Rgb8).unwrap(). Doesn’t support transparency, for that you would have to use RgbImage. - draw_
image2 ⚠ - Draw an image into a widget.
Requires a call to
app::set_visual(Mode::Rgb8).unwrap(). A negative depth flips the image horizontally, while a negative line data flips it vertically. Allows passing a line-data parameter - draw_
line - Draws a line
- draw_

- draw_
text_ n - Like draw_text, however uses FLTK’s
fl_drawwhich takes the length of the string, so it doesn’t need to allocate - draw_
xyline - Draws a horizontal line from (x,y) to (x1,y)
- draw_
xyline2 - Draws a horizontal line from (x,y) to (x1,y), then vertical from (x1,y) to (x1,y2)
- draw_
xyline3 - Draws a horizontal line from (x,y) to (x1,y), then a vertical from (x1,y) to (x1,y2) and then another horizontal from (x1,y2) to (x3,y2)
- draw_
yxline - Draws a vertical line from (x,y) to (x,y1)
- draw_
yxline2 - Draws a vertical line from (x,y) to (x,y1), then a horizontal from (x,y1) to (x2,y1)
- draw_
