Enabling Event Handling on Web Pages

The Web Events dialog, shown in the following image, is displayed when you click the Web Events button in the Define Application dialog Web Options sheet.

When you are using Internet Explorer 4.0 (or higher) for your HTML thin client applications, you can enable:

• The click event for the list box, combo box, option button, table, and check box controls or your user‑defined subclasses of those five control types only.

  The conditions that must be satisfied to enable the click event for controls displayed on Web pages are as follows.

  • The subclassed control must be selected in the Web Events dialog.

  • Browser compatibility mode must be turned off, by ensuring that the Cross Browser Compatibility check box on the Web Options sheet of the Define Application dialog is unchecked.

  • There must be a click event for the control on the form.

• The sheetChg event method in folder controls and your user-defined folder control subclasses.

To enable support for events on your Web pages

1. In the list box, select the control or controls for which the applicable click or sheetChg event is to be enabled on Web pages. (By default, these events are not supported on the controls on Web pages.)

   If you have subclassed any of these controls in your JADE application, those subclasses are also listed to enable you to support the appropriate event on your user-defined controls.

   Use the Ctrl key to make multiple selections, if required.

2. Click the OK button. Alternatively, click the Cancel button to abandon your selections.
