packAll

public static void packAll(org.eclipse.swt.widgets.Control control)

Pack all controls and sub composites

Parameters:

control - Control to start

positionShell

public static void positionShell(org.eclipse.swt.widgets.Shell shell)

Sets the initial location to use for the shell. The default implementation centers the shell horizontally (1/2 of the difference to the left and 1/2 to the right) and vertically (1/3 above and 2/3 below) relative to the parent shell

Parameters:

shell - The shell to set the location

positionShell

public static void positionShell(org.eclipse.swt.widgets.Shell shell,
                                 boolean computeSize)

Sets the initial location to use for the shell. The default implementation centers the shell horizontally (1/2 of the difference to the left and 1/2 to the right) and vertically (1/3 above and 2/3 below) relative to the parent shell

Parameters:

shell - The shell to set the location

computeSize - If true, initialSize is computed from the Shell

positionShell

public static void positionShell(org.eclipse.swt.widgets.Shell shell,
                                 boolean computeSize,
                                 int sameDialogCount)

Sets the initial location to use for the shell. The default implementation centers the shell horizontally (1/2 of the difference to the left and 1/2 to the right) and vertically (1/3 above and 2/3 below) relative to the parent shell

Parameters:

shell - The shell to set the location

computeSize - If true, initialSize is computed from the Shell

sameDialogCount - In the case the same dialog is opened more than once, do not position the Shells on the same position. The sameDialogCount integer tells how many dialogs of the same kind are already open. This number is used to move the new dialog by some pixels.

Parameters:

composite - The control to add the spacer into

cols - Is used as horizontal span in the GridData

rows - Number of labels that are created

setLayoutForAll

public static void setLayoutForAll(org.eclipse.swt.widgets.Control control)

Recursivly update layout for given control and childs

Parameters:

control - The control to set the layout
