* katze_property_proxy:
|
|
* @object: a #GObject
|
|
* @property: the name of a property
|
|
* @hint: a special hint
|
|
*
|
|
* Create a widget of an appropriate type to represent the specified
|
|
* object's property. If the property is writable changes of the value
|
|
* through the widget will be reflected in the value of the property.
|
|
*
|
|
* Supported values for @hint are as follows:
|
|
* "blurb": the blurb of the property will be used to provide a kind
|
|
* of label, instead of the name.
|
|
* "file": the widget created will be particularly suitable for
|
|
* choosing an existing filename.
|
|
* "folder": the widget created will be particularly suitable for
|
|
* choosing an existing folder.
|
|
* "uri": the widget created will be particularly suitable for
|
|
* choosing an existing filename, encoded as an URI.
|
|
* "font": the widget created will be particularly suitable for
|
|
* choosing a variable-width font from installed fonts.
|
|
* Since 0.1.6 the following hints are also supported:
|
|
* "toggle": the widget created will be an empty toggle button. This
|
|
* is only supported with boolean properties.
|
|
* Since 0.1.8 "toggle" creates GtkCheckButton widgets without checkmarks.
|
|
* Since 0.2.0 the following hints are also supported:
|
|
* "font-monospace": the widget created will be particularly suitable for
|
|
* choosing a fixed-width font from installed fonts.
|
|
* Since 0.2.1 the following hints are also supported:
|
|
* "application-TYPE": the widget created will be particularly suitable
|
|
* for choosing an application to open TYPE files, ie. "text/plain".
|
|
* "application-CATEGORY": the widget created will be particularly suitable
|
|
* for choosing an application to open CATEGORY files, ie. "Network".
|
|
* "custom-PROPERTY": the last value of an enumeration will be the "custom"
|
|
* value, where the user may enter text freely, which then updates
|
|
* the property PROPERTY instead. This applies only to enumerations.
|
|
*
|
|
* Any other values for @hint are silently ignored.
|
|
*
|
|
* Since 0.1.2 strings without hints and booleans are truly synchronous
|
|
* including property changes causing the proxy to be updated.
|
|
*
|
|
* Since 0.2.1 the proxy may contain a label if the platform
|
|
* has according widgets.
|
|
*
|
|
* Return value: a new widget
