For example, you can assign an action (which you created independently) to the button or change the assignment dynamically. In the same manner, you can set or change all other properties of a UI element. For this purpose, the class CL_WD_BUTTON, and all other basis classes of UI elements, contains the appropriate method – for the example above, this is the method SET_TEXT. LR_BUTTON = CL_WD_BUTTON=>NEW_BUTTON( text = MY_TEXT ).Ī property like the text of the button can also be used later. MY_TEXT = CL_WD_UTILITIES=>GET_OTR_TEXT_BY_ALIAS( 'MY_TEXT_ALIAS' ). To enhance the above example with a text on the button to be created (the text has been created before in the Online Text Repository): If you want to set a property of the UI element during the dynamic creation, pass the values when you create the element. LR_CONTAINER ?= view->GET_ELEMENT( 'ROOTUIELEMENTCONTAINER' ). LR_FLOW_DATA = CL_WD_FLOW_DATA=>NEW_FLOW_DATA( element = LR_BUTTON ). LR_FLOW_DATA type ref to CL_WD_FLOW_DATA.

The code fragment below shows the steps required to add a UI element of type Button:ĭata: LR_CONTAINER type ref to CL_WD_UIELEMENT_CONTAINER, For this purpose, you must create the layout data for the newly created UI element.

Every UI element has layout data, in accordance with the embedding container. To describe it, a layout is selected for every container: FlowLayout, MatrixLayout, or RowLayout exist (see reference documentation, chapter Layout). To use the dynamic layout manipulation correctly, you must understand the structure of a view: In a view, a number of UI elements is laid out in relation to one another. To make changes to the structure of a view layout, you must use the method WDDOMODIFYVIEW (or a method called within it).įor a complete list of all UI element classes and their methods, refer to the reference part of this documentation. This may be the case if parts of the component are not yet knows at design time. īasically, you should use the dynamic manipulation of the layout – just like the dynamic manipulation of the context – only if it is not possible to construct a component by declarative means. You can also change the dynamic properties of a UI element, bind an event to an action or manipulate the Parameter Mapping of Event Parameters. In this context, you can add as well as remove UI elements. Get 100% faculty guidance and ratings.Under certain conditions, it may be useful to change the layout of a view at runtime.
