String: Returns or sets an initialization script to execute when the widget is created (or reloaded) in the browser.
Use this property to add custom initialization JavaScript that is always executed when the client widget is created. The context (this) of the script is the instance of the widget. You can use the entire qooxdoo and wisej.js api. See #qx and wisej-js.
You may also use the init script to attach events to the widget or to its internal children. Event handlers can also be attached using the ClientEvents collection and the client events methods:

RightToLeft: Returns or sets whether the control's elements are aligned right-to-left to support RTL languages.
When set to Inherit, the control inherits the value of this property from its parent. However, when the control is a top-level control (i.e. Window, Page, Desktop), and the value is set to Inherit, the right-to-left mode is automatically retrieved from the current language.
The behavior of this property is configurable in Default.json setting the "rightToLeft" property to "true", "false", or "auto". The default is "auto", causing the value to be retrieved from the current language.
Boolean: Returns or sets whether the text in the control can be selected in the browser by the user by dragging the pointer. Since 2.5.22 (Default: False
)
Not to be confused with Selectable, which corresponds to the Focusable property. When Selectable is set to true, the text of the control (i.e. a label or a button) can be highlighted in the browser and copied to the clipboard. It will also make the widget "focusable" but only in the browser.
Boolean: Returns or sets whether the control is blocked by the ajax loader. (Default: False
)
Size: Returns or sets the height and width of the control.
String[]: Returns or sets additional theme states to the client widget.
Use this property to manage additional custom states that you may want to add to a widget. The state will update the visualization of the widget using the styles and properties set in the current theme and loaded theme mixins. You can also force the usage of built-in states. However, this property will not return the current states of the widget as updated by the client browser. It only returns the states set by the application.
In addition to setting this property directly, you can also manage it using the related methods:
Since 3.5.5 Add a + after the name of the state to propagate the state to the child controls of the widget. See also AddState.
Int32: Returns or sets the tab order of the control within its container.
Boolean: Returns or sets whether the user can give the focus to this control using the TAB key and the Focusable property is set to true. (Default: True
)
Object: Returns or sets the object that contains data about the control. (Default: null
)
String: Returns or sets the text associated with this control. (Default: ""
)
When AllowHtml is set to true, the text can contain HTML content. If the text contains new lines (CRLF) but doesn't contain HTML elements (at least one "<") all CRLF are automatically substituted with "<BR/>".
String: Returns or sets the tooltip text to show for this control. (Default: ""
)
When using ToolTipText property you can only set the ToolTip text and cannot change the default ToolTip icon set in the theme. To change the ToolTip icon you can either create a custom theme, or a theme mixin, or use the ToolTip extender and the ToolTipText property added by the extender. You can change the default ForeColor, AutomaticDelay, InitialDelay, AutoPopDelay, or enable HTML in ToolTipText by using a ToolTip extender also without setting the ToolTipText property added by the extender.
Int32: Returns or sets the distance, in pixels, between the top edge of the control and the top edge of its container's client area.
