Detailed Description

PangoRendererClass: @draw_glyphs: draws a PangoGlyphString @draw_rectangle: draws a rectangle @draw_error_underline: draws a squiggly line that approximately covers the given rectangle in the style of an underline used to indicate a spelling error. @draw_shape: draw content for a glyph shaped with PangoAttrShape @x, @y are the coordinates of the left edge of the baseline, in user coordinates. @draw_trapezoid: draws a trapezoidal filled area @draw_glyph: draws a single glyph @part_changed: do renderer specific processing when rendering attributes change @begin: Do renderer-specific initialization before drawing @end: Do renderer-specific cleanup after drawing @prepare_run: updates the renderer for a new run @draw_glyph_item: draws a PangoGlyphItem

Class structure for PangoRenderer.

The following vfuncs take user space coordinates in Pango units and have default implementations:

  • draw_glyphs
  • draw_rectangle
  • draw_error_underline
  • draw_shape
  • draw_glyph_item

The default draw_shape implementation draws nothing.

The following vfuncs take device space coordinates as doubles and must be implemented:

  • draw_trapezoid
  • draw_glyph

Since: 1.8
