Package: gtk
Function gtk:label-layout-offsets
Lambda Listgtk:label-layout-offsets (label) ArgumentsReturn Value x -- an integer with the x offset y -- an integer with the y offset Details Obtains the coordinates where the label will draw the pango:layout
object representing the text in the label.
This is useful to convert mouse events into coordinates inside the pango:layout object, e.g. to take some action if some part of the
label is clicked. Of course you will need to create a gtk:event-box widget to receive the events, and pack the label inside it, since labels are windowless. Labels return false from the gtk:widget-has-window function. Remember when using the pango:layout functions you need to convert to and from pixels using the pango:pixels function or the pango:+scale+ constant. Examples(gtk:label-layout-offsets (make-instance 'gtk:label)) => 0 => -9 (gtk:label-layout-offsets (make-instance 'gtk:label :label "text")) => -14 => -9 | See also |
