- The existing Form and List classes have been renamed to ListLegacy and FormLegacy.
- 2 new classes have been created List and Form.
- For the moment both extend the legacy classes and offer a cleaner type safe constructor and showDisplayable and hideDisplayable methods.
- The new classes Form and List can not be used with Display.setCurrent, if used an exception is thrown.
- The methods showDisplayable and hideDisplayable do not affect the the Display.getCurrent state.
Sample usages of the new class
Form and List offer the same constructor and the same showDisplayable/hideDisplayable semantics.
Form as Overlay
public class MyOverlayForm extends Form { public MyOverlayForm() { super("MyTitle", VisualisationMode.DisplayAsOverlay .configAnimation(new AnimationParameters(AnimationParameters.AnimationType.ShiftFromTop))); } public void showHideSample(){ // Showing an overlay from top requires a displable and a top offset. final Displayable disp = null; // Some displayable used for the 0,0 of the top position. this.showDisplayable(new ShowAsOverlayTopParameter(disp, 20)); // hide the thing again. this.hideDisplayable(); } }
