Overview of the HTML Display control
The HTML Display control is used to display a Web page in an application. Thus, in 1 line of code, without using an external browser, your WINDEV applications can display a page of a website. This control is based on Chromium Embedded Framework (CEF).
Creating an HTML Display control
To create an HTML Display control:
  1. On the "Creation" tab, in the "Other controls" group, expand "HTML" and select "HTML Display".
  2. Click at the desired location to create the control. The control appears in the editor.
To view the characteristics of the control, select "Description" in the context menu.
Characteristics of the HTML Display control

Options of the "General" tab

The "General" tab of the control description window allows you to directly enter HTML code or the address of the HTML page to be displayed.
Remark: Any HTML code entered must be between the <HTML> and </HTML> tags.

Options of the "Details" tab, "HTML/JavaScript"

The "Details" tab of the control description window includes the following options in "HTML/JavaScript":
  • Forbid the execution of JavaScript scripts:
    This option is used to allow (or prevent) the execution of scripts called from the HTML code of the control.

    If this option is unchecked, you can:
    • execute JavaScript code in the context of the Web page displayed by the HTML Display control. To do so, use the ExecuteJS function.
    • allow the execution of WLanguage procedures from the JavaScript code via the option "Allow the WLanguage call from the HTML code (JavaScript WL.Execute function)".
      If this option is selected, simply use WL.Execute in the HTML code of the control to execute a WLanguage procedure. The following syntax must be used:
      WL.Execute(<WLanguage procedure name>, <Parameter 1>) [, ... [, <Parameter N>]]] )
      • <WLanguage procedure name> corresponds to the name of the procedure to be executed.
      • <Parameter N> corresponds to the different parameters to be passed to the procedure:
        • Number of parameters:
          • Windows between 0 and N.
        • Type of parameters:
          • Windows The parameters of the WLanguage procedure will be passed according to their type: boolean, string, number, null.
      • WLanguage procedure
        PROCEDURE ProcFromJS(t)
        ToastDisplay("Called from JS: " + t)
      • Code of HTML control:
        s is string = [
        <title> A simple example
        function myFunction()
        <h1> This is an HTML page </h1>
        <p id="demo">A paragraph</p>
        <button type="button" onclick="myFunction()">Try</button>
        HTM_NoName1 = s
  • WINDEV Allow popups:
    With this option, you can enable JavaScript popups (for example, allow opening JavaScript menus as popups).

Options of the "Details" tab, "IE/Edge ActiveX (compatibility)"

The "Details" tab of the control description window includes the Use IE/Edge ActiveX to display content (compatibility) option in IE/Edge ActiveX (compatibility). This option allows you to use the HTML Display control via the Internet Explorer ActiveX plug-in (and no longer Chromium CEF). You can then select the desired rendering engine.
Caution: To use an HTML Display control in "IE/Edge ActiveX (compatibility)" mode:
  • WINDEV in a WINDEV application, Internet Explorer version 4 or later (version 11 recommended) must be installed on the development computer and on the deployment computer. WINDEV's HTML Display control is in Internet Explorer 7 mode.
    To display WEBDEV pages in this control, those pages pages must be generated in HTML + Edge mode.
