From this gesture class, normally one instance is created called
@browser_select_gesture. This gesture is called from
list_browser->event
to deal with modifying the selection of the browser
object.
Unless the aim is to redefine low-level look and feel of the system,
the application programmer does not have to worry about this class.
- browser_select_gesture-scrolling: bool
- If @on,
redirect events to the scroll_bar. This is required to make this gesture
work properly for selecting from a combo-box (menu of menu
<-kind
in windows and text_item with a defined text_item->value_set.
- browser_select_gesture ->drag: event
- If SHIFT is down and list_browser
<-multiple_selection
is @on, the
selection is extended. Otherwise the selection is modified to reflect
the item at the pointer location.
- browser_select_gesture ->initiate: event
- This method saves the selection of the list_browser
object. If the button is released outside the browser, the saved value
is used to restore the selection. See also browser_select_gesture
->terminate.
- browser_select_gesture ->terminate: event
- If this terminates a normal click, list_browser
<-select_message
is executed. If it terminates a double-click, list_browser<-open_message
is executed.
If the gesture is terminated outside the browser, list_browser->change_selectionlist_browser->cancel_message‘.
