Attributes
==========
Widgets are manipulated (mostly) through attributes - and these can all be set by XML attributes.
Derived widgets will have other attributes. Please see their B{New Attributes} sections. The types of the
attributes are pretty straightforward, but note that Position and Color attribute types will also accept
C{fife.Point} and C{fife.Color} values.
- name: String: The identification of the widget, most useful if it is unique within a given widget hiarachy.
This is used to find widgets by L{mapEvents},L{distributeInitialData},L{distributeData} and L{collectData}.
- position: Position: The position relative to the parent widget - or on screen, if this is the root widget.
- size: Position: The real size of the widget (including border and margins). Usually you do not need to set this.
A notable exception is the L{ScrollArea}.
- min_size: Position: The minimal size this widget is allowed to have. This is enforced through the accessor methods
of the actual size attribute.
- max_size: Position: The maximal size this widget is allowed to have. This is enforced through the accessor methods
of the actual size attribute.
- margins: Integer list: The margin clears an area around an element (outside the border) and is completely transparent.
- padding: Integer list: The padding clears an area around the content (inside the border) of the element.
- base_color: Color
- background_color: Color
- foreground_color: Color
- selection_color: Color
- border_color: Color
- outline_color: Color
- font: String: This should identify a font that was loaded via L{loadFonts} before.
- helptext: Unicode: Text which can be used for e.g. tooltips.
- comment: Unicode: Additional text stored by the widget. Not used by PyChan directly. Can be used by the client for additional info about the widget.
- border_size: Integer: The size of the border in pixels.
- position_technique: This can be either "automatic" or "explicit" - only L{Window} has this set to "automatic" which
results in new windows being centered on screen (for now).
If it is set to "explicit" the position attribute will not be touched.
- vexpand: Bool: True. Proportion to expand this widget vertically.
- hexpand: Bool: True. Proportion to expand this widget horizontally.
Convenience Attributes
======================
These attributes are convenience/shorthand versions of above mentioned attributes and assignment will reflect
the associated attributes values. E.g. the following is equivalent::
# Set X position, leave Y alone
widget.x = 10
# Same here
posi = widget.position
widget.position = (10, posi[1])
Here they are.
- x: Integer: The horizontal part of the position attribute.
- y: Integer: The vertical part of the position attribute.
- width: Integer: The horizontal part of the size attribute.
- height: Integer: The vertical part of the size attribute.
