Constructor Detail

AwtTextBox

public AwtTextBox(GralTextBox widgg,
                  java.awt.Container parent,
                  int style,
                  AwtMng mng)

Method Detail

getWidgetImplementation

public java.lang.Object getWidgetImplementation()

Description copied from interface: GralWidgImplAccess_ifc

Returns the implementation class of the widget. If the widget has more as one implementation widgets, this method returns one of the widgets, usual the first important one respectively that widget which represents the implementation layer. A widget of the implementation layer is a SWT.control or a Component.

If more as one widget are part of the GralWidget, use the special GralWidget._wdgImpl class which should contain the references to that implementation widgets.

Specified by:

getWidgetImplementation in interface GralWidgImplAccess_ifc

Overrides:

getWidgetImplementation in class GralWidget.ImplAccess

setBoundsPixel

public void setBoundsPixel(int x,
                           int y,
                           int dx,
                           int dy)

Description copied from interface: GralWidgImplAccess_ifc

Set the bounds of the implementation widget. This is called especially on resize from the panel, but also on creation for comprehensive widgets. If the widget is more comprehensive, consist of more basic widgets, then this operation should care about the parts of the widget.

redrawGthread

public void redrawGthread()

Description copied from interface: GralWidgImplAccess_ifc

This method should be implemented in all Widget implementations of the adapter for the underlying graphic system.
Implementation hints: In SWT it should call redraw(). In AWT this is named 'repaint()'-
It is possible that the widget consists of more as one graphical widget, then all of it should be redrawn. It is possible that some data are set in another thread, they should be applied to the widgets firstly. It is possible that the widget is removed though a repaintGthread-order is pending from the time before deleting, for example if the graphic layout is changed.

See #repaintRequ

setFocusGThread

public boolean setFocusGThread()

Description copied from interface: GralWidgImplAccess_ifc

Sets the focus to the widget. See GralMng_ifc#setFocus(GralWidget).

Returns:

true if it has the focus after this operation. false on any error.

removeWidgetImplementation

public void removeWidgetImplementation()

Description copied from interface: GralWidgImplAccess_ifc

Removes the graphical widget in the graphic.

setVisibleGThread

public void setVisibleGThread(boolean bVisible)

Description copied from interface: GralWidgImplAccess_ifc

Sets the implementation widget(s) visible state. The widgets are really invisible, or they are visible in principle, but they can be covered by other windows or clipping. This method should set the GralWidgetBase.bVisibleState too. Therewith it is able to quest GralWidget.isVisible() in any thread.

Parameters:

bVisible - true then the widget should be visible, false it is set to invisible.

getPixelPositionSize

public GralRectangle getPixelPositionSize()

updateValuesForAction

public void updateValuesForAction()

Description copied from interface: GralWidgImplAccess_ifc

This operation should be called before any action is invoked in the user space. It should update all values from the implementation widget to the GralWidget to enable getting it in the action.
