Class GralWidget.DynamicData

java.lang.Object

org.vishia.gral.base.GralWidget.DynamicData

Enclosing class:

GralWidget

public static final class GralWidget.DynamicData
extends java.lang.Object

This inner class holds the dynamic data of a widget. This data are existent for any widget independent of its type. It can be used in a specific way depending on the widget type.
Hint for visibility in Java: The class and members are public. But the access to the class, the reference GralWidget.dyda is protected. To access any data from a implementing widget, use GralWidget.ImplAccess.dyda() which is protected but visible for the own widget implementation.

Field Detail

whatIsChanged

private java.util.concurrent.atomic.AtomicInteger whatIsChanged

32 bit what is changed, see GralWidget.ImplAccess.chgColorText etc. with this information the redraw in the implementing level can see what is to do.

backColor

public GralColor backColor

Three colors for background, line and text should be convert to the platforms color and used in the draw routine. If this elements are null, the standard color should be used.

backColorNoFocus

public GralColor backColorNoFocus

Three colors for background, line and text should be convert to the platforms color and used in the draw routine. If this elements are null, the standard color should be used.

lineColor

public GralColor lineColor

Three colors for background, line and text should be convert to the platforms color and used in the draw routine. If this elements are null, the standard color should be used.

textColor

public GralColor textColor

Three colors for background, line and text should be convert to the platforms color and used in the draw routine. If this elements are null, the standard color should be used.

textFont

public GralFont textFont

It depends of the pixel size. Therefore set after setToPanel, if GralMng is known.

displayedText

public java.lang.String displayedText

A text to display.

oValues

public java.lang.Object[] oValues

Any specific value.

fValue

public float fValue

minValue

public float minValue

maxValue

public float maxValue

lValue

public long lValue

If a long or int value is given, it is stored here.

visibleInfo

public java.lang.Object visibleInfo

userData

public java.lang.Object userData

fValues

public float[] fValues

bTouchedField

protected boolean bTouchedField

Set to true from any listener of the implementation level if the cursor in the widget is moved or such GUI handling. Then the content won't be overridden by GralWidget.setText(CharSequence) furthermore till the focus is left.

bTextChanged

protected boolean bTextChanged

Set to true from any listener of the implementation level if the data of the widget was changed from GUI handling. If the data are changed from any Gral method invocation, this bit should not set to true. For example a key listener changes the content of a text edit field, then this bit should be set. This bit should be cleared if the GUI-content of the widget is synchronized with the widget data cells. Note that the GUI-content of a widget can be changed only in the GUI thread, whereby the content of the GralWidget.dyda can be read and write in any threat. This bit helps to synchronize.

Method Detail

setChanged

public void setChanged(int mask)

Sets what is changed, Bits defined in GralWidget.ImplAccess.chgColorBack etc. It uses the atomic access capability (see whatIsChanged) to ensure thread safety.

Parameters:

mask - one bit or some bits. ImplAccess.chgXYZ

getChanged

public int getChanged()

Returns the bits what is changed. All bits which were evaluated should be acknowledged via acknChanged(int)

Returns:

acknChanged

public void acknChanged(int mask)

Resets what is changed, Bits defined in GralWidget.ImplAccess.chgColorBack etc. This routine should be called in the draw routine whenever the change was succeeded.

Parameters:

mask - one bit or some bits. ImplAccess.chgXYZ
