Web server - tab of the PmaPanel object

Description:

The link-up of the object to the Web server

Configurators:

Enable as Web component	Specifies whether this object has to be registered as a Web server component
PmaWeb object	Path in the tree of Pma objects to the object PmaWeb, PmaWebFolder or PmaWebLang where the registration is carried out. Macro expression can be used for input (it is evaluated after starting the application).
Web component identifier	Specifies unique identifier of this Web component. The full URL address to this component is then for example: "http://ComputerName:Port/Identifier" Macro expression can be used for input (it is evaluated after starting the application).
View in HTML components list	If checked, then the component will be visible in the component list. Displaying such list is done through the Web object registering this component (Web object PmaWeb, PmaWebFolder or PmaWebLang). If not checked, then the component will not be visible in the list. But it will be accessible through its Web adress. It is useful for system components (e.g. the data offered to another applications), that are not intended to be choosen from Web browsers. When displaying the component list in the Web browser this option can be supressed by pressing the Shift key and by clicking the list title simultaneously. At this moment the list is reopened displaying all the components (including system components).
Refresh period of the Web panel [s]	Specifies how often the page "panel.htm" (dynamic HTML page) reads the XML data and refreshes its content by them. The default value is 3 sec.
Refresh error indication method	Here it is possible to define the visual indication method of panel refresh error (e.g. if connection is lost, if the server stops ...). The visual indication is very important in order to inform the user (client) that the current data is not refreshed correctly. If the visual indication is enabled, then on refresh error the system displays a red text on a yellow background in the upper portion of the window. The visual indication will be in this panel (default) The visual indication will be in the superior panel The visual indication will not be displayed

Note:

By this tab it is possible to register the object as a component into the Web server (i.e. into the PmaWeb, PmaWebFolder or PmaWebLang object).
The client can browse pages of this component only if the "WebRead" permission is fullfiled.
If the client wants to control back from the Web panel, then he must also have the "WebWrite" permission.
If the client wants to call panel methods from the Web panel (see the "Methods" tab of the PmaPanel object), then he must have the "WebMethods" permission.
The client requiring data from this Web component is of the PmWebClient type from the licence point of view.

If the object is registered, then it offers the Web pages in the intranet on the URL address:

http://ComputerName:Port/ComponentId/Page

ComputerName - network computer name on which this PROMOTIC application runs.

Port - port set in the PmaWeb object (if the port equals to 80, then it needn't be entered)

ComponentId - if the component is directly registered into the PmaWeb object, then the text is stated here in the "Web component identifier" configurator on this tab. If the component is registered with the PmaWebFolder or PmaWebLang object, then the identifier of this object is here even before, for example, "IdFolder/IdComponent", etc.

Page - page name that is offered by the object. If the page isn't entered, then the default page will be displayed.
