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. * Since 0.4.1 mnemonics are automatically stripped. * Since 0.2.9 the following hints are also supported: * "languages": the widget will be particularly suitable for choosing * multiple language codes, ie. "de,en_GB". * Since 0.3.6 the following hints are also supported: * "address": the widget will be particularly suitable for typing * a valid URI or IP address and highlight errors. * Since 0.4.0 the following hints are also supported: * "days": the widget will be particularly suitable for choosing * a period of time in days. * * 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 **/ GtkWidget* katze_property_proxy (gpointer object, const gchar* property, const gchar* hint) { GObjectClass* class;
