This class implements the XML 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 object must (!) be used to access the Workspace document.

==BSTxIni Static Functions==
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.
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 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 Member Functions==


The <code>BSTXIni</code> class has the following member functions. See BXMLDoc Member Functions for a list of functions implemented in the parent class.
'''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 <code>$bstxini attach</code> and end with <code>$bstxini detach</code>. See [[Programmer_Guide/Macro_Library/BXMLDoc#Access_control|BXMLDoc access control]] for details.

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.

Usage
bstxini - file
file
the full path of the project file to be removed

Select a project file via a dialog

Misc. Member Functions

Get STx Version

Usage

the full path of the loaded workspace file

Get Application Shell or Name

Usage
$bstxini getapp appname shellid=*
Result
  • if shellid equals *: return the shell-id of the application named appname or an empty string if not running; if multiple instances of this application are running, a blank separated list of shell-ids is returned
  • otherwise: return the name the application executed by the shell with the specified shellid

Member Functions for Setup Element (Profile) Handling

Setup elements (profiles) are xml elements containing settings of STx. All profiles are stored inside the element /CurrentSetup (iref). The argument subsets of the profile functions is appended to the iref (/CurrentSetup/subsets).

Get a List of Profiles

Usage
$bstxini listprofiles table ; tag ; id ; subset
table
a simple table to store results; if no table is passed, it is created
tag
the xml tag of the profiles
id
the id of the current/selected profile of *
subsets
the xml path (partial iref) of the element containing the profiles

Result
Returns a simple or extended table (depends on the profile) containing the profile settings. If the profile id do not exist, it is created from the template tid and then loaded.

Save a Profile

del
if set to 1 the passed table is deleted after saving
tag
the xml tag of the profile
id
the id of the profile
subsets
the xml path (partial iref) of the element containing the profile
Result
0 for success or a non-zero error code
Description
Saves the table in the profile element. If the profile named id exists already, it is replaced, otherwise it is created. If the option del is set to 1 the data table is deleted after saving.

Usage
$bstxini deletesetupelement tag ; id ; subsets
tag
the xml tag of the profile
id
the id of the profile
subsets
the xml path (partial iref) of the element containing the profile
Result
0 if profile was deleted for successfully or a non-zero error code

Uncommon Functions and Functions for internal use only

The following functions are not often used and not so important for user script programming. If you want to know more about these functions look at the comments in the source file BSTXIni.stx

  • LoadAppSetup: load settings of STx standard applications
  • SaveAppSetup: save settings of STx standard applications
  • LoadDefinition: load a xml-doctype definition or the entry defintion of an extended table from the STx configuration
  • CheckVersion: check STx and workspace version and update/upgrade workspace file if necessary
  • Save: save workspace document
