Detailed Description

The ComboCell object implements a cell handler with a "combination-box" pull-down menu in it.

On output, the currently selected menu item is displayed. On input, the user can select from a list in the pull-down menu, or use the keyboard to slect a menu entry by typing the first few menu characters.

void gnc_combo_cell_add_account_menu_item	(	ComboCell *	cell,
		char *	menustr
	)

Add a 'account name' menu item to the list. When testing for equality with the currently selected item, this function will ignore the characters normally used to separate account names.

void gnc_combo_cell_add_ignore_string	(	ComboCell *	cell,

Add a string to a list of strings which, if the cell has that value, will cause the cell to be uneditable on 'enter'.

void gnc_combo_cell_set_autosize	(	ComboCell *	cell,
		gboolean	autosize
	)

Determines whether the popup list autosizes itself or uses all available space. FALSE by default.

}

void gnc_combo_cell_set_complete_char	(	ComboCell *	cell,
		gunichar	complete_char
	)

Sets a character used for special completion processing.

}

void gnc_combo_cell_set_sort_enabled	(	ComboCell *	cell,
		gboolean	enabled
	)

Enable sorting of the menu item's contents. Loading the item is much faster with sorting disabled.

{ 
        PopBox *box;

        if (cell == NULL)
                return;

        unblock_list_signals (cell);
}

void gnc_combo_cell_set_strict	(	ComboCell *	cell,
		gboolean	strict
	)

Determines whether the cell will accept strings not in the menu. Defaults to strict, i.e., only menu items are accepted.

Definition at line 905 of file combocell-gnome.c.

{
        PopBox *box;

        if (cell == NULL)
                return;

        box = cell->cell.gui_private;

        box->strict = strict;
}

void gnc_combo_cell_use_quickfill_cache	(	ComboCell *	cell,
		QuickFill *	shared_qf
	)

Tell the combocell to use a shared QuickFill object. Using this routine can dramatically improve performance when creating combocells with a large number of entries. For example, users with thousands of accounts are complaining about 10-second register startup times, of which 98% of the cpu is spent building the multi-thousand entry quickfill. When a shared quickfill is specified, the combo-cell will not add to nor delete the quickfill; it is the users resonsibility to manage the quickfill object. The combocell will *not* make a copy of teh quickfill.
