• 2016-07-03 Hartmut chg: Now derived from GralCurveView.GraphicImplAccess adequate to the new concept: An implementing widget is derived from its derived class of GralWidget.ImplAccess. Therefore only that base class implements the GralWidgetImpl_ifc.
• 2014-02-03 Hartmut new: CommonCurve#bFreeze: freeze as common property of more as one GralCurveView. Constructor argument.
• 2013-05-19 Hartmut new: Usage of the common SwtGralMouseListener and implementation of the special functionality in the superclass GralCurveView.GralCurveViewMouseAction.
• 2012-08-11 Hartmut now grid with timestamps
• 2012-03-25 Hartmut improved zoom
• 2012-03-17 Hartmut some improvements in paint routine.
• 2012-02-26 Hartmut A lot of details, see GralCurveView
• 2012-02-21 Hartmut Now the CurveView works in the new environment. Some adjustments necessary yet.
• 2011-06-00 Hartmut New concept of GralWidget etc and new Configuration concept with GralCfgBuilder. The old GuiDialogZbnfControlled.class was not use nevermore. But the CurveView was not adapted for that.
• 2010-03-00 Hartmut The curve view was development as basic feature.

Constructor Detail

SwtCurveView

public SwtCurveView(GralCurveView widgg,
                    SwtMng mng)

Method Detail

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

drawTrack

private void drawTrack(GC g,
                       Point size,
                       GralCurveView.Track track,
                       int iTrack,
                       int ixixDataLast)

Draws one track using the ixDataShown indices to the data.

Parameters:

g - graphic context from SWT

size - of the panel in pixel

track - data

iTrack - Index of track, only used for debugging or test outputs.

ixixDataLast - The end index in ixDataShown for this presentation.

drawShiftAreaToLeft

private int drawShiftAreaToLeft(GC g,
                                Point size,
                                int xView,
                                int dxView,
                                int yView,
                                int dyView,
                                int xViewPart,
                                int timeDiff)

Shifts the left draw area to left because only a right part of the curve should be drawn. It is to save calculation time

drawRightOrAll

private void drawRightOrAll(GC g,
                            Point size,
                            int xView,
                            int dxView,
                            int yView,
                            int dyView,
                            int ixDataRight,
                            int xViewPart,
                            int timeDiff,
                            int xp0,
                            boolean bPaintAll)

Draws the curves.

Parameters:

g -

size -

xView -

dxView -

yView -

dyView -

ixDataRight -

xViewPart -

timeDiff -

xp0 -

drawBackground

protected void drawBackground(GC g,
                              Point size,
                              int xView,
                              int yView,
                              int dxView,
                              int dyView)

This routine is called from overridden SwtCurveView.CurveViewSwtWidget.drawBackground(GC, int, int, int, int)

See Also:

It is called in this class in {@link #paintListener} in the {@link PaintListener#paintControl(PaintEvent)} method. It draws the whole content.

Because of saving calculation time there will be drawn only a small peace on right side of the area with the new data normally. The rest inclusive grid lines, curves, text is moved to left. But if the whole window should be refreshed, the whole widget is drawn newly.

stop

void stop()

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.

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

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.

getPixelPositionSize

public GralRectangle getPixelPositionSize()

remove

public boolean remove()

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.
