Class AwtPanel

java.lang.Object

org.vishia.gral.base.GralWidget.ImplAccess

org.vishia.gral.base.GralPanelContent.ImplAccess

org.vishia.gral.awt.AwtPanel

All Implemented Interfaces:

GralWidgImplAccess_ifc

public class AwtPanel
extends GralPanelContent.ImplAccess

Note: a tabbed panel does not exist in AWT. https://coderanch.com/t/330446/java/Tabbed-panel-AWT says: Use Card Layout and small buttons for the tab.

Constant Field Values

itsTabAwt

public java.awt.Container itsTabAwt

The associated tab in a TabFolder if this panel is the main panel of the TabItem, or null if it isn't a main panel of a tab in a tabbed panel.

Note: can't be final because it may be unknown on calling constructor. The property whether a panel is a tab-panel can't be presented with an extra subclass, because this class is the subclass of several Swt panel types. Use the aggregation principle instead multi-inheritance.

panelComposite

public java.awt.Container panelComposite

It is either a Composite or a SwtCanvas

resizeItemListener

protected java.awt.event.ComponentListener resizeItemListener

Constructor Detail

AwtPanel

public AwtPanel(GralPanelContent wdgg)

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

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.

XXXrepaintGthread

public void XXXrepaintGthread()

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.

removeWidgetImplementation

public void removeWidgetImplementation()

Description copied from interface: GralWidgImplAccess_ifc

Removes the graphical widget in the graphic.

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

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.
