The Panel Splitter component creates two resizable panes separated by an adjustable splitter. The panes can be placed horizontally (side by side) or vertically (top to bottom), as determined by the
Orientation attribute. By default,
You can nest Panel Splitter components of different orientations to create multiple vertical and horizontal panes, as shown in the following illustration:
Panel Splitter allows end users to redistribute space between its children. Dragging the adjustable splitter resizes the panes. Clicking the arrow on the splitter collapses the pane (with its contents) in the direction of the arrow.
Like Panel Stretch Layout, Panel Splitter does not accept direct children; children contents can be placed inside facets only. Panel Splitter supports two facets that specify the panes where children contents can be inserted:
<af:panelSplitter ..> <f:facet name="first"> <!-- pane contents here --> </f:facet> <f:facet name="second"> <!-- pane contents here --> </f:facet> </af:panelSplitter>
Panel Splitter is a stretching layout component, that is, it forces specific dimensions onto its children components so that the children fill up available space in the browser when end users resize the browser, resize the panes, or collapse and expand a pane.
When you add a Panel Splitter, JDeveloper uses the following default values for these attributes:
horizontal. This means the panes are arranged side by side (left to right or right to left, depending on the language reading direction). Change the value to
verticalfor panes to be arranged one on top of the other (top to bottom).
false. This means the placement of the adjustable splitter will be measured from the first facet, which is the left or right pane in a horizontal arrangement (depending on the language reading direction), or the top pane in a vertical arrangement. Change the value to
trueto measure the initial position of the splitter from the second facet (which is the right or left pane in a horizontal arrangement, or the bottom pane in a vertical arrangement).
200pixels. This is the distance of the adjustable splitter measured from the first or second facet, depending on the PositionedFromEnd value.
false. This attribute determines whether a pane is collapsed or expanded. By default, the value is
false, which means a pane is expanded. When a pane is expanded, clicking the arrow on the adjustable splitter collapses the pane in the direction of the arrow on the adjustable splitter; clicking the arrow again expands the pane.
In a horizontal arrangement, if
200, the initial position of the adjustable splitter will be 200 pixels from the first facet or left pane (see the first illustration above). In a vertical arrangement, if
200, the initial position of the adjustable splitter will be 200 pixels from the first facet or top pane (see the second illustration above).
false, the arrow on the adjustable splitter points in the direction of the first facet; when
true, the arrow on the adjustable splitter points in the direction of the second facet. By changing
true on the second horizontal Panel Splitter (
s2), the adjustable splitter is now
200px from the end of the right pane (in a left-to-right reading direction), making the center pane larger than the right pane.
