Member Function Documentation

bool PlotMM::ScaleLabels::enabled  )  const [inherited]

Return if the labels are enabled.

Pango::FontDescription* PlotMM::ScaleLabels::font  )  [inherited]

Return a pointer to the labels' font.

Glib::ustring ScaleLabels::format double  d  )  const [inherited]

Format a string from a double value

find a smart way to user-define scale label formatting

Gtk::PositionType PlotMM::ScaleLabels::position  )  const [inherited]

Return where the labels are positioned.

void ScaleLabels::set_enabled bool  b  )  [inherited]

Enable drawing of scalelabels

newsize_ (called automatically)

void ScaleLabels::set_labels int  offs,
const std::map< int, double > &  labels

Set the labels to be drawn

The given map holds double values associated with int positions on a scale. The given offs can be taken as a hint to calculate the right positions for the labels. Normally, the leftmost or upmost border of the scale's Gdk::Window is taken for this offset.

newsize_ (called automatically)

int ScaleLabels::text_height const Glib::ustring &  str  )  const [inherited]

Query the pixel height of the given text when rendered with the current font() settings

int ScaleLabels::text_width const Glib::ustring &  str  )  const [inherited]

Query the pixel width of the given text when rendered with the current font() settings
