Version and history

• 2014-08-16 Hartmut chg: GralTextBox not abstract, using GraphicImplAccess like new concept of all GralWidgets.
• 2012-01-06 Hartmut chg: The GralTextBox.append(CharSequence) etc. methods are implemented in this super class instead in the graphic layer implementation classes. Therefore the methods #appendTextInGThread(CharSequence) and #setTextInGThread(CharSequence) are defined here to implement in the graphic layer. The set- and apppend methods are threadsafe now.

Method Detail

createTextBox

static void createTextBox(GralTextBox widgg,
                          SwtMng mng)

getPixelPositionSize

public GralRectangle getPixelPositionSize()

getWidgetImplementation

public java.lang.Object getWidgetImplementation()

Description copied from interface: GralWidgImpl_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.

setBoundsPixel

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

repaintGthread

public void repaintGthread()

Description copied from interface: GralWidgImpl_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().
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: GralWidgImpl_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.

setVisibleGThread

public void setVisibleGThread(boolean bVisible)

Description copied from interface: GralWidgImpl_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 GralWidget.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.

removeWidgetImplementation

public void removeWidgetImplementation()

Description copied from interface: GralWidgImpl_ifc

Removes the graphical widget in the graphic.
