CHAPTER 4: User-Interface Tools Types of controls 68

User-interface controls

These are types of Control objects that are contained in windows, panels, and groups, and that provide

specific kinds of display and user interaction. Control instances are created by passing the corresponding

type keyword to the add() method of a Window or container; see “Control types and creation parameters”

on page 124.

These examples do not set bounds explicitly on creation, because it is often more useful to set a preferred

size, then allow the layout manager to set the bounds; see “

Automatic layout” on page 86.

Group

Used to visually organize related controls. Unlike Panels, Groups have no title or

visible border. You can use them to create hierarchies of controls, and for fine control

over layout attributes of certain groups of controls within a larger panel. For examples,

see “

Creating more complex arrangements” on page 92.

TabbedPanel

A panel that contains only Tab objects as its immediate children. It has a selection

property that contains the currently active

Tab child. When the value of the selection

property changes, either by a user selecting a different tab, or by a script setting the

property, the

TabbedPanel receives an onChange notification.

The

title property provides an optional label; the titleLayout property places the

label within the panel.

Tab

A general container whose parent is a TabbedPanel, with a selectable tab showing a

localizable

text value. Its size and position are determined by the parent.

Button

Typically used to initiate some action from a window when a user clicks the button;

for example, accepting a dialog’s current settings, canceling a dialog, bringing up a

new dialog, and so on.

X Set the text property to assign a label to identify a Button’s function.

X The onClick callback method provides behavior.

var dlg = new Window(‘dialog’, ‘Alert Box Builder’);

dlg.btnPnl = dlg.add(‘panel’, undefined, ‘Build it’);

dlg.btnPnl.testBtn = dlg.btnPnl.add(‘button’, undefined, ‘Test’);

dlg.btnPnl.buildBtn = dlg.btnPnl.add(‘button’, undefined, ‘Build’,

{name:’ok’});

dlg.btnPnl.cancelBtn = dlg.btnPnl.add(‘button’, undefined, ‘Cancel’,

{name:’cancel’});

dlg.show();

IconButton

A button that displays an icon, with or without a text label. Like a text button, typically

initiates an action in response to a click.

X The image property identifies the icon image; see “Displaying images” on

page 72.

X The title or text property provides an optional label; the titleLayout property

places the label with respect to the image.

X The onClick callback method provides behavior.
