Class GralWidget.ImplAccess

java.lang.Object

org.vishia.gral.base.GralWidget.ImplAccess

All Implemented Interfaces:

GralWidgImplAccess_ifc

Direct Known Subclasses:

GralButton.GraphicImplAccess, GralCanvasArea._GraphicImplAccess_, GralCurveView.GraphicImplAccess, GralHorizontalSelector.GraphicImplAccess, GralHtmlBox.ImplAccess, GralLabel.GraphicImplAccess, GralLed.GraphicImplAccess, GralPanelContent.ImplAccess, GralSlider._GraphicImplAccess_, GralTable.GraphicImplAccess, GralTextField.GraphicImplAccess, GralValueBar.GraphicImplAccess, GralWindow.WindowImplAccess, SwtWidgetSimpleWrapper

Enclosing class:

GralWidget

public abstract static class GralWidget.ImplAccess
extends java.lang.Object
implements GralWidgImplAccess_ifc

This is the super class of all GralWidget access classes of the implementation layer. The protected final operations are called usual from the implementation graphic classes. The non final operations can be overridden and they are called from GralWidget itself. Methods which should be called back by events of the implementation layer. This class is used only for the implementation level of the graphic. It is not intent to use by any application. It is public because the implementation level should accesses it.

wdgimpl

protected java.lang.Object wdgimpl

Aggregation to the widget implementation. This can be a GralWidgetHelper instance which refers the implementation widget or the widget itself. Should be cast due to implementation level.

mngImpl

protected final GralMng.ImplAccess mngImpl

The manager for the implementation. For example SwtMng

pixBounds

public GralRectangle pixBounds

Constructor Detail

ImplAccess

@Deprecated
protected ImplAccess(GralWidget widgg,
                                  GralMng mng)

Deprecated.

ImplAccess

@Deprecated
protected ImplAccess(GralWidget widgg)

Deprecated. use ImplAccess#ImplAccess(GralWidget, GralMng.ImplAccess)

Parameters:

widgg -

ImplAccess

protected ImplAccess(GralWidget widgg,
                     GralMng.ImplAccess mngImpl)

Constructs the base of the graphic implementation widget wrapper (SWT, AWT). Stores the reference to the GralWidget in this.widgg Stores the reference to the graphic implementation widget in GralWidget._wdgImpl Initializes the pos() from the given GralMng.pos() if it is not given by construction.

Parameters:

widgg - The associated derived class of GralWidget.

Method Detail

setPosBounds

public GralRectangle setPosBounds(GralRectangle parentPix)

Set the bounds of the widget from the stored GralPos. It can be overridden for special widgets, for example for depending bounds from content.

Specified by:

setPosBounds in interface GralWidgImplAccess_ifc

Parameters:

parentPix - the bounds of a parent. It is not necessary that this is the bounds of an existing panel. Also a sub region in a panel can be described with it, used for GralWidgComposite.

gralMng

public final GralMng gralMng()

Access to the GralMng from the implementation level.

XXXfocusGained

public final void XXXfocusGained()

This method is not intent to call by user. It may be called from all widget implementation if the focus of the widget is gained. Use GralWidget.setFocus() to set a widget in the focus. It sets the html help for the widget and notifies the widgets in focus for the GralWidgetMng. Don't override this method in the graphic implementation! It should be overridden only in a Gral widget inheritance only if necessary.

setVisibleState

protected void setVisibleState(boolean visible)

Sets the state of the widget whether it seams to be visible. This method should not be invoked by the application. It is It can be override if more as one widget is part of a comprehensive widget.

Parameters:

visible -

actionShow

protected final GralUserAction actionShow()

Access method to GralWidget's method.

dyda

protected final GralWidget.DynamicData dyda()

Access method to GralWidget.dyda.

setTextChanged

protected final void setTextChanged()

Notify that the text is changed in GralWidget.DynamicData.bTextChanged

setDragEnable

protected void setDragEnable(int dragType)

Implementation routine to set receiving a drag event and initializes the drag feature of the widget. A overridden routine should be implemented for the implementation graphic layer widget. This routine is invoked when it isn't overridden, it throws an exception because the drag feature isn't supported for the implementation.

Parameters:

dragType - one of org.vishia.util.KeyCode#dragFiles or ..dragText

setDropEnable

protected void setDropEnable(int dropType)

Implementation routine to set receiving a drop event and initializes the drop feature of the widget.

Parameters:

dropType - one of org.vishia.util.KeyCode#dropFiles or ..dropText

getChanged

protected final int getChanged()

Gets the bits what is changed in the widget's data. The bits are all definitions starting with chg in this class. chgText etc.

Returns:

acknChanged

protected final void acknChanged(int mask)

getActionChange

protected final GralWidget_ifc.ActionChange getActionChange(GralWidget_ifc.ActionChangeWhen when)

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

gralWidgetFromImplData

public static GralWidget gralWidgetFromImplData(java.lang.Object data)

redrawOnlyDynamics

public boolean redrawOnlyDynamics()

Query once in the redraw handler, reset after them see GralWidget.redraw(int, int, boolean)

Returns:

one time true after {@link GralWidget#redraw(int, int, boolean) with true as last argument.
