Detailed Description

Base class for Thumb widget.

The thumb widget is used to compose other widgets (like sliders and scroll bars). You would not normally need to use this widget directly unless you are making a new widget of some type.


Member Function Documentation

std::pair< float, float > CEGUI::Thumb::getHorzRange void   )  const
 

Return a std::pair that describes the current range set for the horizontal movement.

Returns:
a std::pair describing the current horizontal range. The first element is the minimum value, the second element is the maximum value.

std::pair< float, float > CEGUI::Thumb::getVertRange void   )  const
 

Return a std::pair that describes the current range set for the vertical movement.

Returns:
a std::pair describing the current vertical range. The first element is the minimum value, the second element is the maximum value.

bool CEGUI::Thumb::isHorzFree void   )  const [inline]
 

return whether the thumb is movable on the horizontal axis.

Returns:
true if the thumb is movable along the horizontal axis. false if the thumb is fixed on the horizontal axis.

bool CEGUI::Thumb::isHotTracked void   )  const [inline]
 

return whether hot-tracking is enabled or not.

Returns:
true if hot-tracking is enabled. false if hot-tracking is disabled.

bool CEGUI::Thumb::isVertFree void   )  const [inline]
 

return whether the thumb is movable on the vertical axis.

Returns:
true if the thumb is movable along the vertical axis. false if the thumb is fixed on the vertical axis.

void CEGUI::Thumb::onCaptureLost WindowEventArgs e  )  [protected, virtual]
 

Handler called when this window loses capture of mouse inputs.

Parameters:
e WindowEventArgs object whose 'window' pointer field is set to the window that triggered the event. For this event the trigger window is always 'this'.

Reimplemented from CEGUI::ButtonBase.

void CEGUI::Thumb::onMouseButtonDown MouseEventArgs e  )  [protected, virtual]
 

Handler called when a mouse button has been depressed within this window's area.

Parameters:
e MouseEventArgs object. All fields are valid.

Reimplemented from CEGUI::ButtonBase.

void CEGUI::Thumb::onMouseMove MouseEventArgs e  )  [protected, virtual]
 

Handler called when the mouse cursor has been moved within this window's area.

Parameters:
e MouseEventArgs object. All fields are valid.

Reimplemented from CEGUI::ButtonBase.

void CEGUI::Thumb::setHorzFree bool  setting  )  [inline]
 

set whether thumb is movable on the horizontal axis.

Parameters:
setting true to allow movement of thumb along the horizontal axis. false to fix thumb on the horizontal axis.
Returns:
nothing.

void CEGUI::Thumb::setHorzRange float  min,
float  max
 

set the movement range of the thumb for the horizontal axis.

The values specified here are relative to the parent window for the thumb, and are specified in whichever metrics mode is active for the widget.

Parameters:
min the minimum setting for the thumb on the horizontal axis.
max the maximum setting for the thumb on the horizontal axis.
Returns:
Nothing.

void CEGUI::Thumb::setHotTracked bool  setting  )  [inline]
 

set whether the thumb uses hot-tracking.

Parameters:
setting true to enable hot-tracking. false to disable hot-tracking.
Returns:
Nothing.

void CEGUI::Thumb::setVertFree bool  setting  )  [inline]
 

set whether thumb is movable on the vertical axis.

Parameters:
setting true to allow movement of thumb along the vertical axis. false to fix thumb on the vertical axis.
Returns:
nothing.

void CEGUI::Thumb::setVertRange float  min,
float  max
 

set the movement range of the thumb for the vertical axis.

The values specified here are relative to the parent window for the thumb, and are specified in whichever metrics mode is active for the widget.

Parameters:
min the minimum setting for the thumb on the vertical axis.
max the maximum setting for the thumb on the vertical axis.
Returns:
Nothing.

virtual bool CEGUI::Thumb::testClassName_impl const String class_name  )  const [inline, protected, virtual]
 

Return whether this window was inherited from the given class name at some point in the inheritance heirarchy.

Parameters:
class_name The class name that is to be checked.
Returns:
true if this window was inherited from class_name. false if not.

Reimplemented from CEGUI::PushButton.
