Method System.Void Default handler for the event. Override this method in a subclass to provide a default handler for the event. Method System.Void Inserts at in the list of strings stored in . An index to insert . a to insert You can only use this function with combo boxes constructed with . Method System.Void Prepends to the list of strings stored in the . a You can only use this function with combo boxes constructed with . Method System.Void Pops up the menu or dropdown list of . This function is mostly intended for use by accessibility technologies; applications should have little use for it. Method System.Void Removes text at in the list of strings stored in . a You can only use this function with combo boxes constructed with . Method System.Boolean Gets the iter that points to the current active item, if it exists. a a , if it exists. Method System.Void Sets the current active item to be the one referenced by iter. a Method System.Void Hides the menu or dropdown list of this . This function is mostly intended for use by accessibility technologies; applications should have little use for it. Method System.Void Appends to the list of strings stored in . a You can only use this function with combo boxes constructed with . Method System.Void Re-inserts at . a a Note that has already to be packed into the combo box for this to function properly. i Method System.Void Adds the to the end of the combo box. a a If is , then the is allocated no more space than it needs. Any unused space is divided evenly between cells for which is . Method System.Void Packs the into the beginning of the combo box. a a If is , then the is allocated no more space than it needs. Any unused space is divided evenly between cells for which is . Method System.Void Adds an attribute mapping to the list in this combo box. a a , parameter on to be set from the value a , column of the model to get a value from. The is the column of the model to get a value from, and the is the parameter on to be set from the value. So for example if column 2 of the model contains strings, you could have the "text" attribute of a get its values from column 2. Method System.Void Clears all existing attributes previously set with . a Method System.Void Unsets all the mappings on all renderers for this combo box. Method System.Void Sets a data function to use for the combo box. a a The data function is used instead of the standard attributes mapping for setting the column value, and should set the value of the cell renderer as appropriate. may be to remove an older one. Constructor Internal constructor a System.Obsolete(Message=null, IsError=False) Constructor Internal constructor a Constructor Default constructor Constructor Creates a new that uses a Property GLib.GType GType Property a Returns the native GLib.GType value for Combo.
