|
noexcept |
Returns the straight-line distance between where the mouse is now and where it was the last time the button was pressed.
This is quite handy for things like deciding whether the user has moved far enough for it to be considered a drag operation.
|
noexcept |
Returns the difference between the mouse's current x position and where it was when the button was last pressed.
|
noexcept |
Returns the difference between the mouse's current y position and where it was when the button was last pressed.
|
noexcept |
Returns the difference between the mouse's current position and where it was when the button was last pressed.
|
noexcept |
Returns true if the user seems to be performing a drag gesture.
This is only meaningful if called in either a mouseUp() or mouseDrag() method.
It will return true if the user has dragged the mouse more than a few pixels from the place where the mouse-down occurred or the mouse has been held down for a significant amount of time.
Once they have dragged it far enough for this method to return true, it will continue to return true until the mouse-up, even if they move the mouse back to the same location at which the mouse-down happened. This means that it's very handy for objects that can either be clicked on or dragged, as you can use it in the mouseDrag() callback to ignore small movements they might make while trying to click.
|
noexcept |
Returns true if the mouse event is part of a click gesture rather than a drag.
This is effectively the opposite of mouseWasDraggedSinceMouseDown()
|
noexcept |
For a click event, the number of times the mouse was clicked in succession.
So for example a double-click event will return 2, a triple-click 3, etc.
|
noexcept |
Returns the time that the mouse button has been held down for.
If called from a mouseDrag or mouseUp callback, this will return the number of milliseconds since the corresponding mouseDown event occurred. If called in other contexts, e.g. a mouseMove, then the returned value may be 0 or an undefined value.
|
noexcept |
Returns true if the pressure value for this event is meaningful.
|
noexcept |
Returns true if the orientation value for this event is meaningful.
|
noexcept |
Returns true if the rotation value for this event is meaningful.

The x and y positions of the event that is returned will have been adjusted to be relative to the new component. The component pointer that is passed-in must not be null.

| const Point<float> MouseEvent::position |
The position of the mouse when the event occurred.
This value is relative to the top-left of the component to which the event applies (as indicated by the MouseEvent::eventComponent field).
This is a more accurate floating-point version of the position returned by getPosition() and the integer x and y member variables.
| const int MouseEvent::x |
The x-position of the mouse when the event occurred.
This value is relative to the top-left of the component to which the event applies (as indicated by the MouseEvent::eventComponent field).
For a floating-point coordinate, see MouseEvent::position
| const int MouseEvent::y |
The y-position of the mouse when the event occurred.
This value is relative to the top-left of the component to which the event applies (as indicated by the MouseEvent::eventComponent field).
For a floating-point coordinate, see MouseEvent::position
| const ModifierKeys MouseEvent::mods |
The key modifiers associated with the event.
This will let you find out which mouse buttons were down, as well as which modifier keys were held down.
When used for mouse-up events, this will indicate the state of the mouse buttons just before they were released, so that you can tell which button they let go of.
Referenced by LassoComponent< SelectableItemType >::dragLasso().
| const float MouseEvent::pressure |
The pressure of the touch or stylus for this event.
The range is 0 (soft) to 1 (hard). If the input device doesn't provide any pressure data, it may return a negative value here, or 0.0 or 1.0, depending on the platform.
| const float MouseEvent::orientation |
The orientation of the touch input for this event in radians where 0 indicates a touch aligned with the x-axis and pointing from left to right; increasing values indicate rotation in the clockwise direction.
The default is 0.
| const float MouseEvent::rotation |
The rotation of the pen device for this event in radians.
Indicates the clockwise rotation, or twist, of the pen. The default is 0.
| const float MouseEvent::tiltX |
The tilt of the pen device along the x-axis between -1.0 and 1.0.
A positive value indicates a tilt to the right. The default is 0.
| const float MouseEvent::tiltY |
The tilt of the pen device along the y-axis between -1.0 and 1.0.
A positive value indicates a tilt toward the user. The default is 0.
| const Point<float> MouseEvent::mouseDownPosition |
The coordinates of the last place that a mouse button was pressed.
The coordinates are relative to the component specified in MouseEvent::component.
| Component* const MouseEvent::eventComponent |
The component that this event applies to.
This is usually the component that the mouse was over at the time, but for mouse-drag events the mouse could actually be over a different component and the events are still sent to the component that the button was originally pressed on.
The x and y member variables are relative to this component's position.
If you use getEventRelativeTo() to retarget this object to be relative to a different component, this pointer will be updated, but originalComponent remains unchanged.
| Component* const MouseEvent::originalComponent |
The component that the event first occurred on.
If you use getEventRelativeTo() to retarget this object to be relative to a different component, this value remains unchanged to indicate the first component that received it.
| const Time MouseEvent::eventTime |
The time that this mouse-event occurred.
| const Time MouseEvent::mouseDownTime |
The time that the corresponding mouse-down event occurred.
| MouseInputSource MouseEvent::source |
