GET PASTEBOARD DATA


GET PASTEBOARD DATA ( dataType ; data )

Parameter	Type	Description
dataType	String	Type of data to be extracted from pasteboard
data	BLOB	Requested data extracted from the pasteboard

Description

The GET PASTEBOARD DATA command returns, in the BLOB field or in the data variable, the data present in the pasteboard and whose type you pass in dataType. (If the pasteboard contains text copied within 4D, then the BLOB’s character set is likely to be UTF-16.)

Note: In the context of copy/paste operations, the pasteboard corresponds to the clipboard.

In dataType, pass a value specifying the type of data to be retrieved. You can pass a 4D signature, a UTI type (Mac OS), a format name/number (Windows), or a 4-character type (compatibility). For more information about these types, please refer to the Managing Pasteboards section.

Note: You cannot read file type data with this command; in order to do this, you have to use the Get file from pasteboard command.

Example

The following object methods for two buttons copy from and paste data to the array asOptions (pop-up menu, drop-downlist,...) located in a form:

  ` bCopyasOptions object method

 If(Size of array(asOptions)>0) ` Is there something to copy?

    VARIABLE TO BLOB(asOptions;$vxClipData) ` Accumulate the array elements in a BLOB

    CLEAR PASTEBOARD ` Empty the pasteboard

    APPEND DATA TO PASTEBOARD("artx";asOptions) ` Note the data type arbitrarily chosen

 End if

 

  ` bPasteasOptions object method

 If(Pasteboard data size("artx")>0) ` Is there some "artx" data in the pasteboard?

    GET PASTEBOARD DATA("artx";$vxClipData) ` Extract the data from the pasteboard

    BLOB TO VARIABLE($vxClipData;asOptions) ` Populate the array with the BLOB data

    asOptions:=0 ` Reset the selected element for the array

 End if

System variables and sets

If the data is correctly extracted, OK is set to 1; otherwise OK is set to 0 and an error is generated.
