New Form and List

Aktuelle Version vom 21. Juni 2016, 21:03 Uhr

Introduction

• 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();
    }       
}

Form as Widget

public class MyWidgetForm extends Form {
    public MyWidgetForm() {
        super("MyTitle", VisualisationMode.DisplayAsWidget
              .configWidgetIsHideable()
              .configWidgetHasMenu());
    }

    public void showHideSample(){
        // Showing as widget, does not require parameters for the moment.
        this.showDisplayable(null);

        // hide the thing again.
        this.hideDisplayable();
    }

}

Form as Popup

public class MyPopupForm extends Form {
    public MyPopupForm() {
        super("MyTitle", VisualisationMode.DisplayAsPopup);
    }

    public void showHideSample(){
        // Showing as popup, does not require parameters for the moment.
        this.showDisplayable(null);

        // hide the thing again.
        this.hideDisplayable();
    }
}
