my recipe program, I would like to have more than one open at a time, hence the need for multiple instances of the main output form. In Visual Basic I would use MDI. How do I achieve this in Gambas?

BTW… a few sites say create a workspace -  but instructions aren't working from this site:

/comp/gb.form.mdi/workspace/_new - Gambas Documentation

In the parent form, I put in public sub form_open()

dim dwork as workspace  (I also tried dim work as new workspace)

and get the error "unknown identifier: workspace (disparent.class:7)

Have a look here. https://gambaswiki.org/wiki/comp/gb.form.mdi

Make a form and add a WorkSpace.
Make this form your main form. And add a menu to open recipes (mnuOpen)

I guess you already  have a form that shows the recipes now and does all the magic. That is the form you want multiple instances of and don't want to be your main form.
Make sure it has a:
so you can actually instantiate it with a new recipe.

Let's call your recipe form FrmRecipe and the workspace on main form Workspace1. On the event of opening a recipe (from your main form mnuOpen) you could do this:

So, now all you need to do is code the FrmRecipe once for all recipes and reuse by opening an instance for each recipe. Add arguments to _new() of FrmRecipe, so you can pass what you need to the instance just created.

I hope this will get you started. Feel free to ask questions.

 Thankyou for getting back to me on this.

How do I create a workspace to begin with?  I think I may need to add some components, but it isn't recognizing gb.form.mdi.

In project properties, tab components select gb.form.mdi

Workspace icon

Next select you Main form (as mentioned in previous post) and under the 'Properties/Hierachy' box, select tab Special and you will find the Workspace icon

Project properties -> Components

Enjoy…

 Thankyou - I just found the workspace icon.  I do believe their will be magic in my nutrition program today!
