Constructor Detail

SwtPanel

SwtPanel(GralPanelContent panelg)

If this panel represents a Window, it is the GralWindow implementation. The SwtSubWindow does not inherit from GraphicImplAccess. This aggregation is null if the panel is not the window's panel.

SwtPanel

public SwtPanel(GralPanelContent panelg,
                Composite panelSwt,
                boolean notUsed)

Constructs a panel

Parameters:

name - of panel.

mng - The widget manager

panelSwt - may be null, then the GralPanelContent#panelSwtImpl should be set after construction of a derived class.

Method Detail

getPixelPositionSize

public GralRectangle getPixelPositionSize()

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()

This routine takes care about tabbed panels. If GralPanelContent.setFocusedWidget(GralWidgetBase_ifc) was called and the primary widget is a tab, this tab is activated on this panel, which is a tab folder.

removeWidgetImplementation

public void removeWidgetImplementation()

Description copied from interface: GralWidgImplAccess_ifc

Removes the graphical widget in the graphic.

remove

public boolean remove()

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.

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.

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

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.

reportAllContentImpl

public static void reportAllContentImpl(Composite swtComp,
                                        java.lang.Appendable out)

reportAllContentImpl

private static void reportAllContentImpl(Composite swtComp,
                                         java.lang.Appendable out,
                                         int level)
                                  throws java.io.IOException

Throws:

java.io.IOException

outBounds

private static void outBounds(Control swtWdg,
                              java.lang.Appendable out)
                       throws java.io.IOException

Throws:
