Gtk2::Ex::MindMapView::Border::Ellipse : Create a elliptical border.
This document describes Gtk2::Ex::MindMapView::Border::Ellipse version 0.0.1
Gtk2::Ex::MindMapView::Border +----Gtk2::Ex::MindMapView::Border::Ellipse
use Gtk2::Ex::MindMapView::Border::Ellipse;
This module is internal to Gtk2::Ex::MindMapView. It draws a elliptical border for a Gtk2::Ex::MindMapView::Item. This ellipse is instantiated as part of the item creation process in Gtk2::Ex::MindMapView::ItemFactory.
The content that is placed in the border.
The x-coordinate of the upper left corner of the ellipse bounding box.
The y-coordinate of the upper left corner of the ellipse bounding box.
The width of the ellipse bounding box.
The width of the ellipse (in pixels).
The spacing between the ellipse border and the content (in pixels).
new(group=>$group, content=>$content, ...)
Instantiate an elliptical border. You must provide the Gnome2::Canvas::Group on which this border is to place itself. You must also provide a content object.
border_get_image
This method overrides the border_get_image method defined in Border.pm. It instantiates a Gnome2::Canvas::Ellipse.
border_insets
Return the ($top, $left, $bottom, $right) insets for an ellipse. This defined the rectangle inside the ellipse in which content may be placed. At the moment this algoriith is pretty crude. It will be improved.
($top, $left, $bottom, $right)
border_set_x
This method overrides the border_set_x method defined in Border.pm. It sets the value of the border x1 coordinate, and adjusts the x2 value so that the border retains it's width.
border_set_y
This method overrides the border_set_y method defined in Border.pm. It sets the value of the border y1 coordinate, and adjusts the y2 value so that the border retains it's height.
border_set_width
This method overrides the border_set_width method defined in Border.pm. It sets the value of the border x2 coordinate to reflect the new width.
border_set_height
This method overrides the border_set_height method defined in Border.pm. It sets the value of the border y2 coordinate to reflect the new height.
border_set_param
This method overrides the border_set_param method defined in Border.pm. It sets parameters in the Gnome2::Canvas::Ellipse object instantiated by this module.
None.
The algorithm for calculating the rectangle internal to the ellipse in which to place the content is crude, crude, crude. Currently the height and width values are divided by 4 to get insets. Ugh.
The placement of the resize grip(s) could be improved.
No bugs have been reported.
