virtual void MAP::MapWidget::drawOverlay (   )  [protected, virtual]

virtual void MAP::MapWidget::drawWidget (   )  [protected, virtual]

This is the only function that is absolutely neccesary to implement when inheriting Widget to create a custom widget. It is responsible for painting the widget. When it is called, the widget must respect its own padded bounds and not extend rendering beyond that area. Implements MAUI::Widget.

Point MAP::MapWidget::getActualPosition (   )  [protected]

virtual void MAUI::Widget::add (  Widget *  w  )  [virtual, inherited]

Function used to add childs to a widget. The parent of the children will automatically be set. The widget cannot have a parent already. Reimplemented in MAUI::Layout, and MAUI::ListBox.

void MAUI::Widget::setParent (  Widget *  w  )  [inherited]

Function used to set the parent of a widget. The widget will not be added to the parent as a child. The widget cannot have a parent already.

Widget* MAUI::Widget::getParent (   )  [inherited]

Function to retrieve the parent of a widget.

Vector<Widget*>& MAUI::Widget::getChildren (   )  [inherited]

Function to retrieve a reference to the list of childrens for a widget.

const Vector<Widget*>& MAUI::Widget::getChildren (   )  const [inherited]

const version of getChildren()

virtual void MAUI::Widget::draw (  bool  forceDraw = false  )  [virtual, inherited]

Renders the Widget and all its children recursively. Reimplemented in MAUI::ListBox.

virtual void MAUI::Widget::update (   )  [virtual, inherited]

Reimplemented in MAUI::Label, MAUI::Layout, and MAUI::ListBox.

void MAUI::Widget::requestRepaint (   )  [inherited]

Registers an idle listener with the current environment that will redraw the widget and anything else that may be made dirty by doing so. For instance, if the widget is transparent its parent also has to be repainted, and so on recursively.

virtual bool MAUI::Widget::isTransparent (   )  const [virtual, inherited]

Returns whether or not the widget is transparent. A widget is transparent if it has a skin that is transparent in the current selection state (selected/unselected) or if it has no solid background color.

virtual void MAUI::Widget::setSkin (  WidgetSkin *  widgetSkin  )  [virtual, inherited]

Assigns a widget skin to be used during the rendering of the widget. What The skin applies to varies depending on the widget. Labels extend the skin over their entire area, while listboxes apply the skin to each individual item they contain.

void MAUI::Widget::setDrawBackground (  bool  b = true  )  [inherited]

Sets the background drawing state. If b is true, the Widget's background will be drawn - otherwise not. In most cases, the background is either a constant color or a skin.

void MAUI::Widget::setBackgroundColor (  int  col  )  [inherited]

Widget* MAUI::Widget::widgetAt (  const Point &  p  )  [inherited]

Returns a pointer to the first child widget or deeper descendant, surrounding the point. Returns NULL if no widget is found.

Widget* MAUI::Widget::widgetAt (  int  x, int  y )  [inherited]

virtual void MAUI::Widget::setPosition (  int  x, int  y )  [virtual, inherited]

Sets the widget's position relative to its parent. Reimplemented in MAUI::Layout.

const Point& MAUI::Widget::getPosition (   )  const [inherited]

Gets the widget's position relative to its parent.

const Point& MAUI::Widget::getPaddedPosition (   )  const [inherited]

Gets the widget's padded position relative to its parent.

int MAUI::Widget::getWidth (   )  const [inherited]

Returns the width of the widget

int MAUI::Widget::getHeight (   )  const [inherited]

Returns the height of the widget

virtual const Rect& MAUI::Widget::getBounds (   )  [virtual, inherited]

Returns a Rect containing the absolute screen position of the widget together with its dimensions.

virtual bool MAUI::Widget::contains (  const Point &  p  )  [virtual, inherited]

Check if widget surrounds position 'p'.

virtual bool MAUI::Widget::contains (  int  x, int  y )  [virtual, inherited]

Check if widget surrounds position 'x' and 'y'.

virtual void MAUI::Widget::setSelected (  bool  selected = true  )  [virtual, inherited]

Set widget selected state (default: true). Reimplemented in MAUI::EditBox.

bool MAUI::Widget::isSelected (   )  const [inherited]

Is widget selected?.

virtual void MAUI::Widget::setEnabled (  bool  enabled = true  )  [virtual, inherited]

Set Widget enabled state Reimplemented in MAUI::EditBox.

bool MAUI::Widget::isEnabled (   )  const [inherited]

Is Widget enabled ?

virtual void MAUI::Widget::trigger (   )  [virtual, inherited]

This function is called whenever the widget is "triggered", which is roughly equivalent to having been "clicked" on. However, sice MAUI is independant of input facilities, the more input-neutral concept of triggering is used. Reimplemented in MAUI::Layout.

void MAUI::Widget::addWidgetListener (  WidgetListener *  wl  )  [inherited]

Add WidgetListener.

void MAUI::Widget::removeWidgetListener (  WidgetListener *  wl  )  [inherited]

Remove WidgetListener.

Vector<WidgetListener*>& MAUI::Widget::getWidgetListeners (   )  [inherited]

returns a reference the the vector of Widget listeners

void MAUI::Widget::setInputManager (  InputManager *  inputManager  )  [inherited]

Sets the input manager to use for this widget

virtual void MAUI::Widget::setPaddingLeft (  int  l  )  [virtual, inherited]

Set left padding width. Reimplemented in MAUI::Label.

virtual void MAUI::Widget::setPaddingTop (  int  t  )  [virtual, inherited]

Set top padding height. Reimplemented in MAUI::Label.

virtual void MAUI::Widget::setPaddingRight (  int  r  )  [virtual, inherited]

Set right padding width. Reimplemented in MAUI::Label.

virtual void MAUI::Widget::setPaddingBottom (  int  b  )  [virtual, inherited]

Set bottom padding height. Reimplemented in MAUI::Label.

int MAUI::Widget::getPaddingLeft (   )  const [inherited]

Get left padding width.

int MAUI::Widget::getPaddingTop (   )  const [inherited]

Get top padding height.

int MAUI::Widget::getPaddingRight (   )  const [inherited]

Get right padding width.

int MAUI::Widget::getPaddingBottom (   )  const [inherited]

Get bottom padding height.

const Rect& MAUI::Widget::getPaddedBounds (   )  const [inherited]

virtual void MAUI::Widget::setParameter (  const String &  name, const String &  value )  [virtual, inherited]

Reimplemented in MAUI::Label.

void MAUI::Widget::drawBackground (   )  [protected, inherited]

void MAUI::Widget::updateAbsolutePosition (   )  [protected, inherited]

This function is used to regenerate the absolute positions of each widget in the tree. This is done in a depth first manner where each widget takes the parent absolute position and adds it to their own relative position to calculate their absolute position.

void MAUI::Widget::updateAbsolutePositionChildren (  int  x, int  y )  [protected, inherited]

the recursive function used by updateAbsolutePosition().

void MAUI::Widget::updatePaddedBounds (   )  [protected, inherited]

Used to recalculate the padded bounds from the global bounds.

bool MAUI::Widget::isDirty (   )  const [protected, inherited]

Returns the dirty state of the widget, indicating whether it requires to be redrawn or not. When a widget calls requestRepaint(), it's dirty state is set to true. Normally, you shouldn't have to use isDirty() or setDirty() unless possibly when implementing your own widgets.

void MAUI::Widget::setDirty (  bool  d = true  )  [protected, inherited]

Sets the dirty state of the widget.
