Programmer Guide/Macro Library/BSTXIni

File: BSTXIni.STX, linked to library STX.LIB

Parent class: BXMLDoc

See also: BDataSet

This class implements the workspace document. The workspace document contains the STx configuration and the settings and is implemented as a global object which can be accessed from all STx applications and scripts. The user must not create or destroy the workspace object because these functions are performed by the application startup and cleanup macros. At application startup, a BSTXINI instance is created and linked to the global workspace document. The name of is instance is stored in the shell variable BSTXINI. This instance must (!) be used to access the workspace document.

!! Never call the member functions CONSTRUCT, DESTRUCT, CLOSE or LOAD !!

This class also implements a set of static functions which are used by the master application and the application DataSet to manage to file STX.INI which contains the name of the last used workspace file (for program startup) and the project file history. The automatic workspace version update and some installation and licence checks are also implemented by this class, but not described in this documentation.

Important note: A shell or a script should only access or change the content of the workspace document, while it is attached (locked). This is very important, because this document can be (and is often) accessed by all running shells (e.g. STx applications or scripts). A code section accessing the workspace content should start with $bstxini attach and end with $bstxini detach. See BXMLDoc access control for details.

BSTxIni Static Functions

The following functions can be called without a BSTXINI instance.

BSTXINI ?

Get last workspace.

BSTXINI ? file

Set the last workspace.

BSTXINI *

Get the project history list.

BSTXINI + file

Add the project file to the history list.

BSTXINI - file

Remove the project file file from history list.

BSTXINI SelectDataset

Display a dialog asking the user to choose the a project file to load from the list of previous projects. If the user cancels, the last used project is returned, otherwise the user's choice is returned (file path).

BSTXINI Scripts [add file]

Return a list of recently used scripts. If the command add and a file parameter are specified, then the script file is added to the list of recently used scripts.
