|
|
* A hoversel is a button that pops up a list of items (automatically
|
|
* choosing the direction to display) that have a label and, optionally, an
|
|
* icon to select from. It is a convenience widget to avoid the need to do
|
|
* all the piecing together yourself. It is intended for a small number of
|
|
* items in the hoversel menu (no more than 8), though is capable of many
|
|
* more.
|
|
*
|
|
* This widget inherits from the @ref Button one, so that all the
|
|
* functions acting on it also work for hoversel objects.
|
|
*
|
|
* This widget emits the following signals, besides the ones sent from
|
|
* @ref Button:
|
|
* - @c "clicked" - the user clicked the hoversel button and popped up
|
|
* the sel
|
|
* - @c "selected" - an item in the hoversel list is selected. event_info
|
|
* is the item
|
|
* - @c "dismissed" - the hover is dismissed
|
|
*
|
|
* Default content parts of the hoversel widget that you can use for are:
|
|
* @li "icon" - An icon of the hoversel
|
|
*
|
|
* Default text parts of the hoversel widget that you can use for are:
|
|
* @li "default" - Label of the hoversel
|
|
*
|
|
* Supported elm_object common APIs.
