IScreenDesigner,EventListener,org.eclipse.swt.events.FocusListener,org.eclipse.swt.events.KeyListener,org.eclipse.swt.events.MouseListener,org.eclipse.swt.events.MouseMoveListener,org.eclipse.swt.internal.SWTEventListener
public class ScreenDesigner extends Object implements IScreenDesigner, org.eclipse.swt.events.FocusListener, org.eclipse.swt.events.KeyListener, org.eclipse.swt.events.MouseListener, org.eclipse.swt.events.MouseMoveListener
Screen designer interfaces to the TerminalWindow to perform drawing of rectangles and to interface with the mouse and keyboard. Note that the display cannot be drawn correctly if the font size is smaller that 4 pixels vertically or horizontally.

getMarkingConstraints
public org.eclipse.swt.graphics.Rectangle getMarkingConstraints()Gets the rectangle marking constraints. This is used for pop-up windows.- Specified by:
getMarkingConstraintsin interfaceIScreenDesigner- Returns:
- null If no constrains are present.
isHotSpotEnabled
public boolean isHotSpotEnabled()Check for hotspot enabled.- Specified by:
isHotSpotEnabledin interfaceIScreenDesigner
drawLine
Draws a "Business Graphics" line between two points with the current color and the same behavior as for "Java lines".When not using Java 2, the line will be dotted if horizontal or vertical if the line type is not solid (=). The width will be 1.
If the line is invisible, it won't be drawn!
Valid line types are:
SOLID = 0 ALTERNATE = 1 DOT = 2 SHORTDASH = 3 DASHDOT = 4 DOUBLEDOT = 5 LONGDASH = 6 DASHDOUBLEDOT = 7 INVISIBLE = 8
- Returns:
- the phase of the line style.

x- X position, pixel.y- Y position, pixel.returnValue- Returned screen rectangle in [0].- Returns:
- -1 for none, otherwise the handle.
paintFieldRect
public void paintFieldRect(Graphics2D g, IScreenRectangle r, boolean isSelected, org.eclipse.swt.graphics.Rectangle clipRect, boolean isHostField, int xOffset, int yOffset) Paints a screen rectangle property.isWrapped
Checks if a rectangle is wrapped.- Parameters:
r- The rectangle to verify.- Returns:
- true if wrapping screen.
drawHandle
public void drawHandle(ScreenRectangleInfo rectInfo, int handle, Graphics2D g, Color c, int x, int y, boolean draw) Draws a handle at position.hasMark
public boolean hasMark()Checks if terminal has a mark.- Returns:
- Mark flag.
hasSingleMark
public boolean hasSingleMark()Checks if terminal has a single mark.- Returns:
- true if one mark is present.
onDoubleClick
public void onDoubleClick(int x, int y) Marks the host field.- Specified by:
onDoubleClickin interfaceIScreenDesigner
createHostFieldToolTip
public static org.eclipse.swt.widgets.Composite createHostFieldToolTip(HostField hostField, org.eclipse.swt.widgets.Composite parent) Creates a tooltip composite for a host field.
