Version, history and license:

• 2016-08-31 Hartmut chg: Now disposes the window in shellListener
• 2015-05-31 Hartmut setFocusGThread() now regards the GralPanelContent.setPrimaryWidget(GralWidget).
• 2015-04-27 Hartmut new GralWindow_ifc.windRemoveOnClose
• 2012-07-13 Hartmut new: getPixelSize(), chg: getPixelPositionSize() in all implementations. A swt.widget.Shell now returns the absolute position and the real size of its client area without menu and title bar.
• 2012-06-29 Hartmut new: GralWindow.setResizeAction(GralUserAction) now for both ctors, resize on subwindow works.
• 2012-03-10 Hartmut new: calls invisibleSetAction.userActionGui if the window is set invisible by pressing the X closing icon.
• 2012-02-11 Hartmut chg: The menu of the window is managed now in SwtMenu. Instance refered with menuBar
• 2011-11-27 Hartmut chg: #addMenuBarArea9ItemGThread(String, String, GralUserAction) moved from SwtPrimaryWindow to this, because the capability to have a menu bar may needed on a sub-window too.
• 2011-11-18 Hartmut chg: SwtSubWindow#SwtSubWindow(String, Display, String, int, GralMng) now gets an int-property instead boolean 'exclusive'. A window has more as one property. Constants are defined in GralWindow_ifc.windExclusive etc.
• 2011-11-10 Hartmut chg: move all files from mainGuiSwt to gral.swt, dissolve of package mainGuiSwt
• 2011-11-09 Hartmut chg: renamed from SubWindowSwt to SwtSubWindow
• 2011-11-01 Hartmut new: shellListener and disposeListener added, but empty yet.
• 2011-10-31 Hartmut new: mouseListener and GralWindow.setMouseAction(GralUserAction).
• 2011-10-30 Hartmut new: resizeListener, GralWindow.setResizeAction(GralUserAction) etc: Not this class is base of SwtPrimaryWindow and contains this capabilities yet.
• 2011-10-30 Hartmut new: getPixelPositionSize() and setBoundsPixel(int, int, int, int) to support pixel-orientation too. Note it isn't a concept of GRAL anyway, but it is needed.
• 2011-10-20 Hartmut chg: GralMng as parameter of constructor: The GralWidget refers it, it should be initialized.
• 2011-10-15 Hartmut new: removeWidgetImplementation().
• 2011-09-23 Hartmut bugfix: setFocus() called in GralWindow.setWindowVisible(boolean), it hasn't the focus automatically.
• 2011-09-18 Hartmut chg: Now it is a SubWindowSwt and inherits from the new GralWindow. Some methods GralWidget.setBackColor(GralColor, int), GralWindow.setWindowVisible(boolean) etc added to comply the interface and super class definitions.
• 2011-09-03 Hartmut creation as wrapper arround a SWT.Shell inherits GralPanelContent.

Method Detail

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.

Specified by:

getWidgetImplementation in interface GralWidgImpl_ifc

removeWidgetImplementation

public void removeWidgetImplementation()

Description copied from interface: GralWidgImpl_ifc

Removes the graphical widget in the graphic.

Specified by:

removeWidgetImplementation in interface GralWidgImpl_ifc

getPixelPositionSize

public GralRectangle getPixelPositionSize()

Description copied from class: GralPanelContent.ImplAccess

Returns the absolute position of this panel on screen and its size. If it is a main window, the useable area of the window without title and menu bar is returned.

Specified by:

getPixelPositionSize in interface GralWidgImpl_ifc

Specified by:

getPixelPositionSize in class GralPanelContent.ImplAccess

getPixelSize

public GralRectangle getPixelSize()

Description copied from class: GralPanelContent.ImplAccess

Returns the size of this panel in pixel.

Specified by:

getPixelSize in class GralPanelContent.ImplAccess

Returns:

the x and y is 0, the dy and dy is the size.

setBoundsPixel

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

Returns the size of the working area without border, menu and title of the window. Uses Scrollable.getClientArea() to get the size.

Specified by:

setBoundsPixel in interface GralWidgImpl_ifc

stop

void stop()

setFocusGThread

public boolean setFocusGThread()

Description copied from interface: GralWidgImpl_ifc

Sets the focus to the widget. See GralMng_ifc#setFocus(GralWidget).

Specified by:

setFocusGThread in interface GralWidgImpl_ifc

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.

Specified by:

setVisibleGThread in interface GralWidgImpl_ifc

Parameters:

bVisible - true then the widget should be visible, false it is set to invisible.

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.
