Field Detail

SASH_WIDTH

public int SASH_WIDTH
Constructor Detail

SashForm

public SashForm(
Composite parent,
                int style)
Constructs a new instance of this class given its parent and a style value describing its behavior and appearance.

The style value is either one of the style constants defined in class SWT which is applicable to instances of this class, or must be built by bitwise OR'ing together (that is, using the int "|" operator) two or more of those SWT style constants. The class description lists the style constants that are applicable to the class. Style bits are also inherited from superclasses.

Parameters:
parent - a widget which will be the parent of the new instance (cannot be null)
style - the style of widget to construct
Throws:
IllegalArgumentException -
  • ERROR_NULL_ARGUMENT - if the parent is null
SWTException -
  • ERROR_THREAD_INVALID_ACCESS - if not called from the thread that created the parent
See Also:
SWT.HORIZONTAL, SWT.VERTICAL, getStyle()
Method Detail

getOrientation

public int getOrientation()
Returns SWT.HORIZONTAL if the controls in the SashForm are laid out side by side or SWT.VERTICAL if the controls in the SashForm are laid out top to bottom.

Returns:
SWT.HORIZONTAL or SWT.VERTICAL

getSashWidth

public int getSashWidth()
Returns the width of the sashes when the controls in the SashForm are laid out.

Returns:
the width of the sashes
Throws:
SWTException -
  • ERROR_WIDGET_DISPOSED - if the receiver has been disposed
  • ERROR_THREAD_INVALID_ACCESS - if not called from the thread that created the receiver
Since:
1.2

getStyle

public int getStyle()
Description copied from class: Widget
Returns the receiver's style information.

Note that the value which is returned by this method may not match the value which was provided to the constructor when the receiver was created. This can occur when the underlying operating system does not support a particular combination of requested styles. For example, if the platform widget used to implement a particular SWT widget always has scroll bars, the result of calling this method would always have the SWT.H_SCROLL and SWT.V_SCROLL bits set.

Overrides:
getStyle in class Widget
Returns:
the style bits

getMaximizedControl

public 
Control getMaximizedControl()
Answer the control that currently is maximized in the SashForm. This value may be null.

Returns:
the control that currently is maximized or null

getWeights

public int[] getWeights()
Answer the relative weight of each child in the SashForm. The weight represents the percent of the total width (if SashForm has Horizontal orientation) or total height (if SashForm has Vertical orientation) each control occupies. The weights are returned in order of the creation of the widgets (weight[0] corresponds to the weight of the first child created).

Returns:
the relative weight of each child
Throws:
SWTException -
  • ERROR_WIDGET_DISPOSED - if the receiver has been disposed
  • ERROR_THREAD_INVALID_ACCESS - if not called from the thread that created the receiver

setOrientation

public void setOrientation(int orientation)
If orientation is SWT.HORIZONTAL, lay the controls in the SashForm out side by side. If orientation is SWT.VERTICAL, lay the controls in the SashForm out top to bottom.

Parameters:
orientation - SWT.HORIZONTAL or SWT.VERTICAL
Throws:
SWTException -
  • ERROR_WIDGET_DISPOSED - if the receiver has been disposed
  • ERROR_THREAD_INVALID_ACCESS - if not called from the thread that created the receiver
  • ERROR_INVALID_ARGUMENT - if the value of orientation is not SWT.HORIZONTAL or SWT.VERTICAL

setBackground

public void setBackground(
Color color)
Description copied from class: Control
Sets the receiver's background color to the color specified by the argument, or to the default system color for the control if the argument is null.

Overrides:
setBackground in class Control
Parameters:
color - the new color (or null)

setForeground

public void setForeground(
Color color)
Description copied from class: Control
Sets the receiver's foreground color to the color specified by the argument, or to the default system color for the control if the argument is null.

Overrides:
setForeground in class Control
Parameters:
color - the new color (or null)

setLayout

public void setLayout(
Layout layout)
Sets the layout which is associated with the receiver to be the argument which may be null.

Note: No Layout can be set on this Control because it already manages the size and position of its children.

Overrides:
setLayout in class Composite
Parameters:
layout - the receiver's new layout or null
Throws:
SWTException -
  • ERROR_WIDGET_DISPOSED - if the receiver has been disposed
  • ERROR_THREAD_INVALID_ACCESS - if not called from the thread that created the receiver

setMaximizedControl

public void setMaximizedControl(
Control control)
Specify the control that should take up the entire client area of the SashForm. If one control has been maximized, and this method is called with a different control, the previous control will be minimized and the new control will be maximized. If the value of control is null, the SashForm will minimize all controls and return to the default layout where all controls are laid out separated by sashes.

Parameters:
control - the control to be maximized or null
Throws:
SWTException -
  • ERROR_WIDGET_DISPOSED - if the receiver has been disposed
  • ERROR_THREAD_INVALID_ACCESS - if not called from the thread that created the receiver
Since:
1.2

setSashWidth

public void setSashWidth(int width)
Specify the width of the sashes when the controls in the SashForm are laid out.

Parameters:
width - the width of the sashes
Throws:
SWTException -
  • ERROR_WIDGET_DISPOSED - if the receiver has been disposed
  • ERROR_THREAD_INVALID_ACCESS - if not called from the thread that created the receiver
Since:
1.2

setWeights

public void setWeights(int[] weights)
Specify the relative weight of each child in the SashForm. This will determine what percent of the total width (if SashForm has Horizontal orientation) or total height (if SashForm has Vertical orientation) each control will occupy. The weights must be positive values and there must be an entry for each non-sash child of the SashForm.

Parameters:
weights - the relative weight of each child
Throws:
SWTException -
  • ERROR_WIDGET_DISPOSED - if the receiver has been disposed
  • ERROR_THREAD_INVALID_ACCESS - if not called from the thread that created the receiver
  • ERROR_INVALID_ARGUMENT - if the weights value is null or of incorrect length (must match the number of children)
