HowTo: Create a Component in the GXflow Client

This documentation is valid for:

This article explains how to create a new component in the GXflow Client. Also, for the sake of example, it will explain how to create a component that calls a Web Panel and displays the parameters received.
It is important to understand that more useful components than the explained below can be created and used, but for simplicity purposes, this article is focused on explaining how to create a component and not on what the component does or how it looks.

Step 1 - Create a new Web Panel

Create a new Web Panel object called "ReceiveParameters".

Rules

Parm(in:&mychar);

Variables

mychar (Type: Character)

Add a Textblock with "Received:" caption and the "mychar" variable to the layout.

Step 2 - Run the GXflow Standard Client

First, open your GXflow Standard Client application. To do so, right-click on one of your Business Process Diagram objects and select Run:

Step 3 - Login

Log in with a user that has the GXflow Backend Administrator role —see GXflow Management Console for details on how to manage users and roles.

Note: when using GeneXus Access Manager the GAM Backoffice must be used in order to manage users, roles and permissions.

Step 4 - Open the Components component

Open the Components component by selecting it. It is located under the GXflow Backend node.

The GXflow Components dialog will be opened.

Step 5 - Create a new Component

Press the button, and set the properties as follows:

It is important to set the Object property to "ReceiveParameters"—the name of the Web Panel created in step 1.

Note: when using GeneXus Access Manager, a permission will be created once the component has been created. The permission will be created with the name "{COMPONENT_ID}"; in this case: "ReceiveParameters".

Step 6 - Add the new Component to a Menu

Next, in order to use the newly created Component you must add it to GXflow Menus. For simplicity purposes, add it to an existing Component.

To do so, open the "Menus" component by selecting it—it is located under the GXflow Backend node:

Select the "Desktop" menu and press the button; a dialog box will be displayed for you to select the component you want to add or remove from the menu.

Add the "ReceiveParameters" component by selecting it from the "Components" grid and using the . Press OK.

Step 7 - Done!

Lastly, test your component. To do so, add permissions for the "ReceiveParameters" component to a role, and log in with a user that has permissions to use the newly created component and the "Desktop" menu— for example, use WFADMINISTRATOR.

Next, open the "ReceiveParameters" component.
