public SwtValueBar(GralValueBar widgg,
                   SwtMng mng)

Creates a value bar.

size - The size of text in button, use 'A' or 'B' for small - bold

Method Detail

setBounds

public void setBounds()

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

setBorderAndColorsImpl

public void setBorderAndColorsImpl(java.lang.String[] sColorLevels)

Specified by:

setBorderAndColorsImpl in class GralValueBar.GraphicImplAccess

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.

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.

paintRoutine

protected void paintRoutine(SwtValueBar.BarWidget wdgs,
                            org.eclipse.swt.events.PaintEvent e)

stop

void stop()

setBoundsPixel

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

removeWidgetImplementation

public void removeWidgetImplementation()

Description copied from interface: GralWidgImpl_ifc

Removes the graphical widget in the graphic.

getPixelPositionSize

public GralRectangle getPixelPositionSize()
