 org.eclipse.ui.internal.dnd.SwtUtil
| SwtUtil | | public class SwtUtil (Code) | | Contains static methods for manipulating SWT controls
since:
3.0 |
| Method Summary | |
| public static Control | controlThatCovers(Control toTest)
Returns the control that is covering the given control, or null if none. | | public static Control | findCommonAncestor(Control control1, Control control2)
| | public static Control | findControl(Display displayToSearch, Point locationToFind)
Finds and returns the most specific SWT control at the given location. | | public static Control | findControl(Control[] toSearch, Point locationToFind)
Searches the given list of controls for a control containing the given point. | | public static Control | findControl(Composite toSearch, Point locationToFind)
| | public static Control[] | getAncestors(Control theControl)
| | public static boolean | intersectsAnyMonitor(Display display, Rectangle someRectangle)
Returns true iff the given rectangle is located in the client area of any
monitor. | | public static boolean | isChild(Control potentialParent, Control childToTest)
Determines if one control is a child of another. | | public static boolean | isDisposed(Control toTest)
| | public static boolean | isFocusAncestor(Control potentialParent)
|
| controlThatCovers | | public static Control controlThatCovers(Control toTest)(Code) | | Returns the control that is covering the given control, or null if none.
Parameters:
toTest - control to test a control that obscures the test control or null if none |
| findCommonAncestor | | public static Control findCommonAncestor(Control control1, Control control2)(Code) | | |
| findControl | | public static Control findControl(Display displayToSearch, Point locationToFind)(Code) | | Finds and returns the most specific SWT control at the given location.
(Note: this does a DFS on the SWT widget hierarchy, which is slow).
Parameters:
displayToSearch -
Parameters:
locationToFind - |
| findControl | | public static Control findControl(Control[] toSearch, Point locationToFind)(Code) | | Searches the given list of controls for a control containing the given point.
If the array contains any composites, those composites will be recursively
searched to find the most specific child that contains the point.
Parameters:
toSearch - an array of composites
Parameters:
locationToFind - a point (in display coordinates) the most specific Control that overlaps the given point, or null if none |
| findControl | | public static Control findControl(Composite toSearch, Point locationToFind)(Code) | | Finds the control in the given location
Parameters:
toSearch -
Parameters:
locationToFind - location (in display coordinates) |
| getAncestors | | public static Control[] getAncestors(Control theControl)(Code) | | |
| intersectsAnyMonitor | | public static boolean intersectsAnyMonitor(Display display, Rectangle someRectangle)(Code) | | Returns true iff the given rectangle is located in the client area of any
monitor.
Parameters:
someRectangle - a rectangle in display coordinates (not null) true iff the given point can be seen on any monitor |
| isChild | | public static boolean isChild(Control potentialParent, Control childToTest)(Code) | | Determines if one control is a child of another. Returns true iff the second
argument is a child of the first (or the same object).
Parameters:
potentialParent -
Parameters:
childToTest - |
| isDisposed | | public static boolean isDisposed(Control toTest)(Code) | | Returns true if the given control is null or has been disposed
Parameters:
toTest - the control to test false if it is safe to invoke methods on the given control |
| isFocusAncestor | | public static boolean isFocusAncestor(Control potentialParent)(Code) | | |
