If the constraint is omitted, the component is placed in the next available cell. The table layout container expects something like this:Ĭontainer.addComponent(tableConstraint, component) Other layout managers expect components to be added on their own. The table layout is a constraint based layout (similar to the border layout). It is largely inspired by the HTML table tag and also influenced by AWT's GridBagLayout. The table layout is a part of the table component discussed later, however it is quite useful on its own. Top.getUnselectedStyle().setBgColor(0xff0000) Label underCenter = new Label("Under Center") Label centeredLabel = new Label("Center") ĬenteredLabel.getUnselectedStyle().setBgTransparency(100) ĬenteredLabel.getUnselectedStyle().setBgColor(0xff) The z-ordering is determined by the order in which the components are placed into the parent container.The last component added is the one on top.įinal Form mainForm = new Form("Coordinate Layout") Unlike the other standard layouts in LWUIT the coordinate layout allows positioning components on top of one another to achieve z-ordering. If the container is laid out to a larger size, for example, 190x300 the component in the center would still be centered. This is essential since the available size for a container might change at runtime based on font size, screen rotation, etcetera.įor example, a coordinate layout for 200x200 will show a 20x20 component placed in the 90x90 position exactly in the center, regardless of the actual size of the container. ![]() ![]() Instead coordinate layout accepts positions as "relative" and calculates the actual position based on available space. The coordinate layout allows developers to position components within an X/Y location, however, it doesn't guarantee the position won't change and doesn't determine absolute positions. Unlike other layout managers coordinate layout assigns a component an absolute position in relation to the space available within the UI.
