Encapsulates parameters used in a set cursor request.
The LClientCursor class encapsulates the parameters requested by the client through LPointer::setCursorRequest().
You can retrieve the last cursor request for a specific client using LClient::lastCursorRequest().
Clients create an LCursorRole for the compositor to use as the cursor. This class holds a reference to the role along with the LPointerEnterEvent that triggered the request.
Additionally, it includes a property indicating whether the client intends to hide the cursor or not.
This information gets overridden when the same client makes another LPointer::setCursorRequest() or when the associated LCursorRole is destroyed.
When assigned to an LCursor through LCursor::setCursor(), the LCursor's texture and hotspot automatically change based on the values of the associated LCursorRole. However, the cursor size remains user-defined.
If the LCursorRole surface is unmapped or destroyed after being assigned to an LCursor, the default cursor is automatically restored.
|
inlinenoexcept |
Indicates if the client wants to hide the cursor.
Returns true
if the client has never made a set cursor request. If the LCursorRole is destroyed and this method returns true
, and one of the client surfaces has pointer focus, then the default cursor should be restored.
true
if the client intends to hide the cursor, false
otherwise.
|
inlinenoexcept |
Returns the pointer enter event sent to the client that initiated the cursor request.
|
inlinenoexcept |
Returns the LCursorRole the client used for this cursor.
If the user has never made a set cursor request or the LCursorRole was destroyed, this returns nullptr
.
nullptr
if no set cursor request has been made or the LCursorRole is destroyed.
