widgetPushColormap :: Colormap -> IO ()gtk Graphics.UI.Gtk.Abstract.Widget Pushes cmap onto a global stack of colormaps; the topmost colormap on the stack will be used to create all widgets. Remove cmap with widgetPopColormap. There's little reason to use this function.
widgetSetColormap :: WidgetClass self => self -> Colormap -> IO ()gtk Graphics.UI.Gtk.Abstract.Widget Sets the colormap for the widget to the given value. Widget must not have been previously realized. This probably should only be used from an init function (i.e. from the constructor for the widget).
widgetSetDefaultColormap :: Colormap -> IO ()gtk Graphics.UI.Gtk.Abstract.Widget Sets the default colormap to use when creating widgets. widgetPushColormap is a better function to use if you only want to affect a few widgets, rather than all widgets.
widgetSetMapped :: WidgetClass widget => widget -> Bool -> IO ()gtk Graphics.UI.Gtk.Abstract.Widget Marks the widget as being realized. This function should only ever be called in a derived widget's “map” or “unmap” implementation.
cairoFontMapGetDefault :: IO FontMapgtk Graphics.UI.Gtk.Cairo Retrieve the default FontMap that contains a list of available fonts.
- One purpose of creating an explicit FontMap is to set a different scaling factor between font sizes (in points, pt) and Cairo units (in pixels). The default is 96dpi (dots per inch) which corresponds to an average screen as output medium. A 10pt font will therefore scale to 10pt * (1/72 pt/inch) * (96 pixel/inch) = 13.3 pixel.
cairoFontMapGetResolution :: FontMap -> IO Doublegtk Graphics.UI.Gtk.Cairo Ask for the scaling factor between font size and Cairo units.
- Value is in dots per inch (dpi). See cairoFontMapGetDefault.
cairoFontMapSetResolution :: FontMap -> Double -> IO ()gtk Graphics.UI.Gtk.Cairo Set the scaling factor between font size and Cairo units.
- Value is in dots per inch (dpi). See cairoFontMapGetDefault.
