A control template is a set of controls that can be re-used in several windows or pages. - WINDEV and WINDEV Mobile allow you to create control templates that can be used in the windows.
- WEBDEV allows you to create control templates that can be used in pages.
A control template can be edited or modified; when a template is modified, these modifications can be applied to all the windows or pages that use this template. The control templates are used to: - group a set of controls for a specific purpose.
- make the controls independent of the window that is hosting them.
Furthermore, the control templates are saved in a ".WDT" file that can be easily transferred from one project to another. Benefit compared to supercontrols: The modifications made to the control templates can be automatically applied to all the windows (or pages) that use the control template. Benefits compared to internal windows or pages: The control templates are directly inserted, visible and modifiable in the window or in the page. They can be directly overridden in the window or page that uses the control template. Creating a control template Creating a control template from existing controls To create a control template from existing controls: - Select the controls that must be included in the control template.
- On the "Modification" tab, in the "Transformations" group, expand "Refactoring and swapping" and select "Create a control template from the selection".
Remarks: - You can also select "Refactoring .. Create a control template from the selection" in the context menu of the selection.
- You have the ability to create a template of a control template, which means a a control template based on another control template.
Special cases - The context menus are available in the control templates:
- If the window includes context menus, the context menus of the control template must have different names.
- The context menus of the control template are added to the context menus of the window.
- If there are two identical control templates with context menus in a window, the override of the context menu of the control template applies to both control templates.
- If several control templates found in a window have the same source, updating a control template triggers the update of all the control templates that use the same source in the window.
Testing a control template To run the test of a control template: - Open the control template in the editor.
- Click the "Go" button ("Run the window test" or "Run the page test" icon).
To use a control template: - Open the window or the page in which the control template must be included.
- Create a Control Template control: on the "Creation" tab, in the "Containers" group, click "Control template".
- Select the control template that will be included in the window or in the page.
Caution: The control template is associated once and for all to the "Control Template" control. To change the association, you must delete the "Control Template" control and re-create it. - Validate and position the control in the window or in the page.
Remark: A control template created with WINDEV (for a window) cannot be used in a page and a control template created in WEBDEV (in a page) cannot be used in a window. Renaming a control template If a control template is renamed, the link with the elements that use this template is lost. This link can be restored via the window that lists the templates: on the "Window" tab, in the "Templates" group, expand "Templates" and select "List of templates used".
