EnumElement (Function)

EnumSubElement (Function)

In french: EnumèreSousElément

Allows you to enumerate the sub-elements of a project element. This function can be run even if the element is not opened.

In a loop, this function can be used to enumerate the controls found in a window (or in a page) of a project.

Remark: This function cannot be used on the reports or on the queries.

Example

See additional examples

// Enumerate the controls found in a project window
ControlName is string = EnumSubElement("MyWindow", enumFirst)
// Browse all the controls
WHILE ControlName <> ""
Trace(ControlName)
// Go to the next control
ControlName = EnumSubElement("MyWindow")
END

// Browse the panes in a tab control
ControlName is string = EnumSubElement("WIN_Window1.Tab1", enumFirst + enumPane)

// Browse all the panes
WHILE ControlName <> ""
// Go to the next pane
Trace(ControlName)
ControlName = EnumSubElement("WIN_Window1.Tab1", enumPane)
END

// Enumerate the controls found in a project page
ControlName is string = EnumSubElement("MyPage", enumFirst)
// Browse all the controls
WHILE ControlName <> ""
Trace(ControlName)
// Go to the next control
ControlName = EnumSubElement("MyPage")
END

// Browse the window controls and display their type and caption.
sParent is string = "WIN_EDIT_CUSTOMER"
sControlName is string = EnumSubElement(sParent, enumFirst)
WHILE sControlName <> ""

// Full name of the control
sFullName is string = sParent + "." + sControlName
// Retrieve the type of the element
nType is int = {sFullName, indGPW}..Type

// If it is a group of controls or a tab
IF nType = typTab OR nType = typTable OR nType = typToolbar OR ...
nType = typToolbox OR nType = typSuperControl THEN
// Enumerate the controls found inside
Trace(sFullName)
ELSE
// No action if it is a menu option
IF nType <> typMenuOption THEN
// Add the element into the trace
Trace(sFullName, nType, {sFullName, indGPW}..Caption, ...
{sFullName, indGPW}..Group)
END
END

// Next control
sControlName = EnumSubElement(sParent)
END

Syntax

<Result> = EnumSubElement(<Element> [, <Option>])

<Result>: Character string

Full name of element found (<Window/Page Name>.<Control Name> for example),
Empty string ("") if no element was found.

<Element>: Character string (with quotes)

Full name of element to enumerate. For a control, this parameter has the following format: <Window/Page Name>.<Control Name> ("MyWindow.MyTable" for example).

<Option>: Optional constant

Parameter that must be specified during the first call to the function (to start the enumeration). This parameter is not required to continue the enumeration.
enumSideBar Enumerates the panes found in a sidebar.
This constant is not available.
enumGroup Enumerates the groups found in a window or in a page
enumContextualMenu Enumerates the popup menus found in a window.
This constant is not available.
enumMainMenu Enumerates the drop-down menus found in a window. You also have the ability to use EnumMenu.
This constant is not available.
enumFirst Initializes the enumeration
enumPane Enumerates the panes found in the tabs or ribbons.
This constant is not available.
Caution: the following combinations must be used to initialize the browse:
enumFirst to enumerate the controls found in a window or in a page
enumFirst + enumGroup to enumerate the groups found in a window or in a page
enumFirst + enumPane to enumerate the panes found in a tab or in a ribbon
enumFirst + enumContextualMenu to enumerate the popup menus
enumFirst + enumSideBar to enumerate the panes found in a sidebar
enumFirst + enumMainMenu to enumerate the main menus of a window or page

Remarks

Enumerating the panes found in the tabs (or in the ribbons)

By default, EnumSubElement used on a tab enumerates all the controls found in all the panes without displaying the pane.

When the enumPane constant is specified, EnumSubElement used on a tab enumerates all the tabs (but not the controls found in the tabs). The result has the following format: "<n>" where <n> is the tab number. To find out the tab caption, use ..Caption.

To enumerate the controls found in each pane, an enumeration must be performed on the pane from its number:

EnumSubElement("<window>.<tab>.<n>")

Remark: ..Count is used to find out the number of tab panes.

Enumerating the panes found in a sidebar

By default, EnumSubElement used on a sidebar enumerates all the controls found in all the panes without displaying the pane.

If the enumSideBar constant is specified, EnumSubElement used on a sidebar enumerates all the panes (but not the controls found in the panes). The result has the following format: "<n>.<caption>" where <n> is the number of the pane and <caption> its caption.

To enumerate the controls found in each pane, an enumeration must be performed on the pane from its number:

EnumSubElement("<Window/Page>.<SideBar>.<n>")

Limit

This function cannot be used to enumerate the sub-elements of an element found in a component.
