A fairly large set of key bindings are supported * by default. If the entered text is longer than the allocation * of the widget, the widget will scroll so that the cursor * position is visible. * * When using an entry for passwords and other sensitive information, * it can be put into "password mode" using gtk_entry_set_visibility(). * In this mode, entered text is displayed using a 'invisible' character. * By default, GTK+ picks the best invisible character that is available * in the current font, but it can be changed with * gtk_entry_set_invisible_char(). Since 2.16, GTK+ displays a warning * when Caps Lock or input methods might interfere with entering text in * a password entry. The warning can be turned off with the * #GtkEntry:caps-lock-warning property. * * Since 2.16, GtkEntry has the ability to display progress or activity * information behind the text. To make an entry display such information, * use gtk_entry_set_progress_fraction() or gtk_entry_set_progress_pulse_step(). * * Additionally, GtkEntry can show icons at either side of the entry. These * icons can be activatable by clicking, can be set up as drag source and * can have tooltips. To add an icon, use gtk_entry_set_icon_from_gicon() or * one of the various other functions that set an icon from a stock id, an * icon name or a pixbuf. To trigger an action when the user clicks an icon, * connect to the #GtkEntry::icon-press signal. To allow DND operations * from an icon, use gtk_entry_set_icon_drag_source(). To set a tooltip on * an icon, use gtk_entry_set_icon_tooltip_text() or the corresponding function * for markup. * * Note that functionality or information that is only available by clicking * on an icon in an entry may not be accessible at all to users which are not * able to use a mouse or other pointing device. It is therefore recommended * that any such functionality should also be available by other means, e.g. * via the context menu of the entry. */ #define GTK_ENTRY_COMPLETION_KEY "gtk-entry-completion-key" #define MIN_ENTRY_WIDTH 150 #define DRAW_TIMEOUT 20 #define COMPLETION_TIMEOUT 300 #define PASSWORD_HINT_MAX 8 #define MAX_ICONS 2 #define IS_VALID_ICON_POSITION(pos) \ ((pos) == GTK_ENTRY_ICON_PRIMARY || \ (pos) == GTK_ENTRY_ICON_SECONDARY) static const GtkBorder default_inner_border = { 2, 2, 2, 2 };
