SashForm

The SashForm is a composite control that lays out its children in a row or column arrangement (as specified by the orientation) and places a Sash between each child. One child may be maximized to occupy the entire size of the SashForm. The relative sizes of the children may be specified using weights. <dl> <dt>Styles:</dt> <dd>HORIZONTAL, VERTICAL, SMOOTH</dd> </dl>

Constructors

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

Functions

getMaximizedControl Control getMaximizedControl(): Answer the control that currently is maximized in the SashForm. This value may be null.
getOrientation 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.
getSashWidth int getSashWidth(): Returns the width of the sashes when the controls in the SashForm are laid out.
getWeights 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).
setLayout 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.
setMaximizedControl 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.
setOrientation 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.
setSashWidth void setSashWidth(int width): Specify the width of the sashes when the controls in the SashForm are laid out.
setWeights 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.

Variables

SASH_WIDTH int SASH_WIDTH;: The width of all sashes in the form.

Inherited Members

From Composite

changed void changed(Control[] changed): Clears any data that has been cached by a Layout for all widgets that are in the parent hierarchy of the changed control up to and including the receiver. If an ancestor does not have a layout, it is skipped.
getBackgroundMode int getBackgroundMode(): Returns the receiver's background drawing mode. This will be one of the following constants defined in class <code>SWT</code>: <code>INHERIT_NONE</code>, <code>INHERIT_DEFAULT</code>, <code>INHERTIT_FORCE</code>.
getChildren Control[] getChildren(): Returns a (possibly empty) array containing the receiver's children. Children are returned in the order that they are drawn. The topmost control appears at the beginning of the array. Subsequent controls draw beneath this control and appear later in the array. Note: This is not the actual structure used by the receiver to maintain its list of children, so modifying the array will not affect the receiver.
getLayout Layout getLayout(): Returns layout which is associated with the receiver, or null if one has not been set.
getLayoutDeferred bool getLayoutDeferred(): Returns <code>true</code> if the receiver has deferred the performing of layout, and <code>false</code> otherwise.
getTabList Control[] getTabList(): Gets the (possibly empty) tabbing order for the control.
isLayoutDeferred bool isLayoutDeferred(): Returns <code>true</code> if the receiver or any ancestor up to and including the receiver's nearest ancestor shell has deferred the performing of layouts. Otherwise, <code>false</code> is returned.
layout void layout(): If the receiver has a layout, asks the layout to lay out (that is, set the size and location of) the receiver's children. If the receiver does not have a layout, do nothing. This is equivalent to calling <code>layout(true)</code>. Note: Layout is different from painting. If a child is moved or resized such that an area in the parent is exposed, then the parent will paint. If no child is affected, the parent will not paint.
layout void layout(bool changed): If the receiver has a layout, asks the layout to lay out (that is, set the size and location of) the receiver's children. If the argument is <code>true</code> the layout must not rely on any information it has cached about the immediate children. If it is <code>false</code> the layout may (potentially) optimize the work it is doing by assuming that none of the receiver's children has changed state since the last layout. If the receiver does not have a layout, do nothing. If a child is resized as a result of a call to layout, the resize event will invoke the layout of the child. The layout will cascade down through all child widgets in the receiver's widget tree until a child is encountered that does not resize. Note that a layout due to a resize will not flush any cached information (same as <code>layout(false)</code>). Note: Layout is different from painting. If a child is moved or resized such that an area in the parent is exposed, then the parent will paint. If no child is affected, the parent will not paint.
layout void layout(bool changed, bool all): If the receiver has a layout, asks the layout to lay out (that is, set the size and location of) the receiver's children. If the changed argument is <code>true</code> the layout must not rely on any information it has cached about its children. If it is <code>false</code> the layout may (potentially) optimize the work it is doing by assuming that none of the receiver's children has changed state since the last layout. If the all argument is <code>true</code> the layout will cascade down through all child widgets in the receiver's widget tree, regardless of whether the child has changed size. The changed argument is applied to all layouts. If the all argument is <code>false</code>, the layout will not cascade down through all child widgets in the receiver's widget tree. However, if a child is resized as a result of a call to layout, the resize event will invoke the layout of the child. Note that a layout due to a resize will not flush any cached information (same as <code>layout(false)</code>). Note: Layout is different from painting. If a child is moved or resized such that an area in the parent is exposed, then the parent will paint. If no child is affected, the parent will not paint.
layout void layout(Control[] changed): Forces a lay out (that is, sets the size and location) of all widgets that are in the parent hierarchy of the changed control up to and including the receiver. The layouts in the hierarchy must not rely on any information cached about the changed control or any of its ancestors. The layout may (potentially) optimize the work it is doing by assuming that none of the peers of the changed control have changed state since the last layout. If an ancestor does not have a layout, skip it. Note: Layout is different from painting. If a child is moved or resized such that an area in the parent is exposed, then the parent will paint. If no child is affected, the parent will not paint.
setBackgroundMode void setBackgroundMode(int mode): Sets the background drawing mode to the argument which should be one of the following constants defined in class <code>SWT</code>: <code>INHERIT_NONE</code>, <code>INHERIT_DEFAULT</code>, <code>INHERIT_FORCE</code>.
setLayout void setLayout(Layout layout): Sets the layout which is associated with the receiver to be the argument which may be null.
setLayoutDeferred void setLayoutDeferred(bool defer): If the argument is <code>true</code>, causes subsequent layout operations in the receiver or any of its children to be ignored. No layout of any kind can occur in the receiver or any of its children until the flag is set to false. Layout operations that occurred while the flag was <code>true</code> are remembered and when the flag is set to <code>false</code>, the layout operations are performed in an optimized manner. Nested calls to this method are stacked.
setTabList void setTabList(Control[] tabList): Sets the tabbing order for the specified controls to match the order that they occur in the argument list.
