OpenSheetWithParmInTabGroup ( <var>sheetrefvar</var>, <var>parameter</var> {, <var>windowtype</var> }, <var>siblingname</var>, <var>sheetname</var> ) |
| Argument | Description |
|---|---|
| sheetrefvar | The name of any window variable that is not an MDI frame window. OpenSheetWithParmInTabGroup places a reference to the open sheet in sheetrefvar. |
| parameter | The parameter you want to store in the Message object when the sheet is opened. Parameter must have one of these datatypes:
|
| windowtype (optional) | A string whose value is the datatype of the window you want to open. The datatype of windowtype must be the same or a descendant of sheetrefvar. |
| siblingname | The name of a sibling window in either a docked state or in a non-document tab group. The sheet opens in that tab group. |
| sheetname | A unique string identifier for the sheet, which is used when layout is persisted. |
Returns
Integer. Returns 1 if it succeeds and -1 if an error occurs. If any argument’s value
is null, OpenSheetWithParmInTabGroup returns null. In some cases,
such as if the windowtype argument is invalid,
OpenSheetWithParmInTabGroup throws a runtime error and does
not return a value; therefore, it is recommended that you both test the return value
and wrap the function call in a try-catch block.
Usage
The first sheet opened in a main window cannot be opened using
OpenSheetInTabGroup or
OpenSheetWithParmInTabGroup. To create a tab group, open the
first sheet as a docked sheet and then use that sheet as the
siblingname argument.
The system Message object has three properties for storing data. Depending on the
datatype of the parameter specified for
OpenSheetWithParmFromDockingState, scripts for the opened
sheet would check one of the following properties.
| Message object property | Argument datatype |
|---|---|
| Message.DoubleParm | Double |
| Message.PowerObjectParm | PowerObject (PowerBuilder objects, including user-defined structures) |
| Message.StringParm | String |
In the opened window, it is a good idea to access the value passed in the Message
object immediately (because some other script may use the Message object for another
purpose).
object. The object must exist when you refer to it later or you get a null object
reference, which causes an error. For example, if you pass the name of a control on
a window that is being closed, that control will not exist when a script accesses
the parameter.
