In CaptainCasa you can define styles definitions for components. A style definition is a definition of a set of default attribute values that are applied to the component. In case you want to differenciate between different usage types of the component you can apply multiple styles - and use the stylevariant attribute to select between.
Text that is shown and (dependent from the component type) edited inside the component. The terminator is a decimal byte value.
Text that is shown as hint when the user stays with the mouse on top of the control for a while.
| ...anytext... | Text that is displayed as tooltip. |
| server:true | Indicator that tooltip for the component is managed on server side. The actionListener will be invokde with events BaseActionEventTooltipStarted and BaseActionEventTooltipEnde. On server side you may implement some modeless popup in order to show some more complex tooltip |
| server:true;opendelay:1000 | Duration in milliseconds after which a tooltip event is triggered when the user moves the mouse on top of this component |
When true then the user can define the interim points him/herself. In this case the update of interim points will be written back into the property that is assigned to attribute INTERIMPOINTS.
| false | (default) |
| true | With editing of interim points |
