[Base] Call MRI on forms or form controls from form document

Postby Arineckaig » Wed Mar 02, 2011 2:13 pm

I have been asked to post this code which some people have found helpful.

Hanya's MRI extension is an invaluable tool as an UNO object browser that will display properties, methods, interfaces and services relevant to any UNO object passed to it. It can readily be called by inserting a line into a macro. Often, however, I found I had a need to call MRI directly from a form document to check the properties, methods, interfaces and services applicable to a particular form or form control in that document.

To this end, and with essential help from Hanya, I have been using a routine that can be called whether the form document is in 'edit' or in 'direct' mode to display a form control tree similar to that used by the 'form navigator'. Double clicking the name of any form or form control shown in the list automatically runs MRI on the 'model' of that object and on its 'view' if the object has one. Unless the 'Auto close' box is checked the tree control remains open so that MRI can be run on other objects listed therein.

I store the module as a separate library under 'My Macros' and call its 'Main' routine from an icon added to the form document toolbar.

You use it at your own risk, but hopefully it should cause no damage as it only displays on the screen a tree control and one or more MRI results. Some routines at the end seem to be empty, but they must be included to prevent errors arising from the use of mouse and button event listeners. Please PM me if you find errors or have problems.

Edit 26 March 2011: Updated the code to include display of MRI scan of the 'View' of controls contained within a Grid control. Access to these View is only obtained through the View of the Grid Control and then using .GetByIndex to reach the View of the contained control, but never if the containing form document is in edit mode
Edit 26 Sep 2011: I have prepared a first draft of a User Guide for this macro that can be downloaded from https://www.dropbox.com/pri/get/Public/MRI%20ControlTreeUserGuide.pdf?_subject_uid=10552709&w=AADk-i5Jq8WvCcuSAXgRT38ky4_tbKP37wrgc2nOMS5ORA.
Edits 11 Oct 2011, 30 June & 3 Jul 2012: Update code to access 'View' of columns in a Grid Control unless form document is in Edit Mode.

Re: Call MRI on forms or form controls direct from form docu

Postby Villeroy » Wed Mar 02, 2011 3:20 pm

Whenever I use some macros with Base forms, I never walk from the top of the hierarchy (active document>forms>form>getByName...). I prefer an entirely event driven style.
I use to bind the event I'm interested in to the Basic wrapper MRI.Module1.mri which passes the event struct with the source object and possibly some additional information. The initial object is the event struct, property "Source" is the calling object (form or form control) and getParent takes me one level higher in the object hierarchy.
This way I get 90% of the event driven code directly recorded by MRI.
Please, edit this topic's initial post and add "[Solved]" to the subject line if your problem has been solved.

Villeroy, many thanks for your contribution - instructive and imaginative as ever. I suspect that many of us have developed shortcuts to uncover the undocumented potentials within MRI. If this thread merely brings some of them into the light of day it will hopefully have served its purpose.
When this issue has been resolved, it would help other users of the forum if you add the word - [Solved] - to the Subject line of your 1st post (edit button top right).

Re: [Base]Call MRI on forms or form controls from form docum

Postby Arineckaig » Fri Mar 23, 2012 1:06 pm

I have prepared and attached a meaningless Base file to provide a demonstration of the MRI tree control. It requires the MRI extension to have been added and the demonstration will not work unless the “MRILib” macros have already been stored in “My Macros and Dialogs”. A brief 'explanation' form document is included in the demonstration file. If, however, regular use is to be made of the macro it should be stored and used as described in the Tutorial mentioned in my first post above, that can still be downloaded from http://db.tt/AvMnUCAf..https://www.dropbox.com/pri/get/Public/MRI%20ControlTreeUserGuide.pdf?_subject_uid=10552709&w=AADk-i5Jq8WvCcuSAXgRT38ky4_tbKP37wrgc2nOMS5ORA
