I'm attempting to create a custom stencil, and one of the ways I want to make developing this easier is to have children reference the dimensions of parent stencils (parametric design).
In the below pictures I'm showing the values I want to refer to on the parent, as well as confirming the Shape Name is Shape.7.
But when I attempt to refer to it on the child shape, I'm told I have an invalid formula, even though the autocompletion in Visio is listing the available fields for me which appears to confirm I'm referencing it correctly:
In this example stencil I have two shapes, Parent and Child. This is the stencil I used to create the screenshots above. I simply want the Child shape to inherit constant values from the Parent shape rather than copying them, so that modifying the parent would automatically update the child.
Instead of Shape.7 I think you need to use the Sheet name e.g. Sheet.5 or similar.

As the document said, TreeView in GTK4 has been deprecated since 4.10. The recommended replacement for it is ColumnView. However, I can't find clear documentation or example about how to build a treeView-like widget in GTK4 by ColumnView.
I found maybe TreeExpander related to it but I still don't know how to deal with it.
A very brief outline of what I did:
Familiarize yourself with how the new dynamic list widgets (Gtk.GridView and Gtk.ColumnView) work for a flat model (GLib.ListStore). There is example code in the Demo app.
Create a Gtk.TreeListModelCreateModelFunc function that takes a model item as a parameter and, if that item has children (e.g. is a folder in a filesystem model), creates and returns a Gtk.ListStore to hold the children. If the child items are already available then they can also be appended to the child model here. This means the child items are preloaded whether or not the row is expanded. For startup performance reasons, you might want to arrange to load them when the row is actually expanded which is more difficult - in this case you have to add a dummy child to the model else the expander will not be displayed.
Create a Gtk.SignalListItemFactory.
In the setup handler, create a display widget as usual then instead of using your display widget as child of the Gtk.ListItem, you create a Gtk.TreeExpander, and make that the child the Gtk.ListItem and make the display widget a child of the expander.
In the bind handler, get the display widget and model item from the supplied object. A complication here is that the object may be a Gtk.TreeListRow whose item might be another Gtk.TreeListRow so getting to the model item is harder. Bind the widget to the model item as usual. Then get the Gtk.TreeListRow from the Gtk.ListItem position and set the expander's list-row property to it.
If you delayed loading the child items then you would need to detect when the row is first expanded. You can connect to the notify signal for the Gtk.TreeListRow.expanded property to do this.
Use a Gtk.TreeListModel with a GLib.ListStore as its root_store as the model of a Gtk.ColumnView (after wrapping in Gtk.SelectionModel as usual). You must set the passthrough property to false else no expanders appear. If you are loading child items on demand then autoexpand should also be false.
If you are using a Gtk.ColumnView with multiple columns, you only need add the expander to the first column. Otherwise the factory signal handlers or similar to the flat model except the bind handler needs to be adapted for Gtk.TreeListRow parameter.
Simplifications and performance improvements may well be possible or later versions of Gtk4 may introduce some conveniences to make it less fiddly.
I am working on a file browser implementation using the above strategy, currently at https://github.com/elementary/files/tree/gtk4-treelistmodel but this may be merged into other branches (or abandoned!). Note that this branch is under development and contains unresolved bugs but the display of items works.
I'm new to AnyLogic and trying to figure out how Agent-based models should be set there. There is a famous Epidemic model, which I'm trying to reproduce. Most tutorials on classical ABM deal with old GUI settings.
For example, in version 8.5+, which is actual now, the Environment object (that was used for positioning of layouts) has been deprecated.
Now I see that new object Canvas is used to put the layout with agents on the page. But the structure of source code file is a bit unclear for me and I've failed to find relevant description how Canvas can be set for the purpose. (Besides I'm not sure that this is recommended way of doing this task.)
Question: I would love to learn the right way to arbitrary position the area with agents on the page. Below you may see what I get by default.
After some playing around, the 'minimalistic' functionality is as follows.
One should create some population with arbitrary name Person (population name people adds automatically).
The following structure of the Project is to be reproduced (arbitrary names are marked with yellow).
Comment: after adding a Canvas called mapCanvas one adds the function setCanvasCellColor with following body:
mapCanvas.fillCircle(person.getX(), person.getY(), 3, color);
It is clear that former two arguments stand for coordinates of a given point, then its size (i.e. 3) and color. Do not forget to add two arguments used in the body, namely, person as Person and color as Color.
From Entry Action of the statechart named state call the just made function. I've put black color here just for the sake of demonstration; chartreuse constant gets used instead in the Epidemic example.
main.setCanvasCellColor(this, black);
Finally, you may run the model to get the following picture.
Note
If one is reluctant to bother with Canvas, use Main - Presentation - xxx_presentation and click Draw agent with offset to this position checkbox.
I have a custom toolbox with a foo element.
I would like the foo to be green on an class diagram and red on flow chart diagram by default.
Adding more than one stereotype to non- UML type is impossible (as far as I know).
Is it possible to create 2 toolboxes- one for class diagrams and one for flow charts, specifying the default diagram for each toolbox in the profile?
Not quite the way you describe it.
Toolboxes don't specify which diagram they open, it's the other way around: you create a custom diagram type and associate it with a toolbox. Different custom diagrams may use the same custom toolbox.
You can create two custom diagram types, one for class ("Logical") and one for flow chart ("Activity"), but if you're only after getting the same stereotyped element (foo) to display differently in the diagrams, you don't need to.
The solution is to create a shape script for the stereotype, which checks the diagram type and changes the color accordingly. The diagram type can be queried from the shape script using the diagram.type property (for the base UML diagram type), or diagram.mdgtype (for the custom diagram type, if you've defined one). There is no need to create an Add-In, as another answer suggests, at least not in EA 11.
Check the help file under Extending UML Models -- MDG Technology SDK -- Shape Scripts -- Write Scripts -- Display Element/Connector Properties.
A simple script might look like this:
shape main {
if (hasproperty("diagram.type", "Logical")) {
setfillcolor(0, 255, 70);
} else if (hasproperty("diagram.type", "Activity")) {
setfillcolor(255, 87, 87);
}
drawnativeshape();
};
No. You need to have two different stereotypes. The target diagram is independent of the element. If you want the element appear different on the type of the diagram where you use it you need to adapt the shape script so it calls an add-in which detects the diagram type.
Well, writing the last sentence I would not know how to detect the diagram where the element in question is in. Needs investigation. But other than that - no solution I know of.
Edit: Since the add-in just receives the element GUID it has no way to figure out the diagram from where the call is made. Probably worth a feature request. But the time where we saw those realized in the next build are gone (since more than 10 years).
A last though: template packages. I almost never used them. Maybe they offer coloring depending on diagram/element.
Edit2: Last resort EA_OnPostNewDiagramObject. Catch that and you can get all information you need to apply the color.
I'm trying to use ILabelDecorators to decorate icons in the TableViewer.
I use two-column table to show properties of some model object. The first column displays the property name, the second column it the property value.
Some objects in the second column may have icons and I want these icons decorated.
The number of rows in the table is not constant and depends on the kind of the model.
The problem is that the content provider for the TableViewer assumed to provide the 'row model' objects, so I have to use some containers to pack both property name and value.
Then it comes to decorating, Eclipse uses these containers, but not their 'value' parts, to select the appropriate decorators, and to pass as the argument to the decorate() procedure.
As the result, decoration code are never called, because the class of these containers (I use simple Object array) does not match any classes declared in the enablement sections of the decorator elements in the plugin.xml.
Moreover, even if I do not restrict the decorators by classes, these containers are passed to the decorate() procedure in all my decorators, so I have to make all decorators know about these containers existence, which is quite weird.
At last, I have found some solution, I use an IAdapterFactory object to convert containers to their values. But it seem an overkill a bit.
Does anyone know more simple solutions?
I have a list of widgets which needs to be sorted. I want to create a container for these list of widgets to re-sort them each time new widget is added. How can I do it?
I can see the following ways:
a straightforward way is place them into arraylist and sort via Comparator, but after a new element is added we have to remove all list from container and add them again, in a new order.
use some sorting container. i have found only CellTable for this. But actually I dont need its rich functionality - I have only one column, dont need to sort on user events, only when new element added or removed, - so is there something else I can utilize in my use case?
GWT 2.4
PS
Actually, I am looking for something, that can be expressed like "widget container backed by widget collection", i.e. I change collection - container changes its contents, how can I implement this, or where can I find it?
PPS
The widgets can be different, thats why I dont think I can use CellTable easily.
There is no straightforward way of re-sorting the elements in the DOM after you add a new widget.
When the widgets are attached you cannot just move them (change their position in the document structure) without detaching and re-attaching.
Well, with absolute positioning you can just change the left-top coordinates to move the items, if it is what you need.
I had a similar problem to solve when I had to sort TreeItem elements (no built-in sort method available). As a workaround, I read all the children into the list and remove them from the parent widget at the same time, then sort these items using Comparator and add them back to parent from the sorted list. Everything is in a single sort() method, which encapsulates all required functionality and kind of simplifies understanding of this code.
"widget container backed by widget collection"
I would like to learn about one like that that also can do sorting and re-attaching on the fly. But it still will be backed by the same detaching-attaching I assume. I would recommend you to write one yourself, that will fit your particular needs. Either you need a Tree or a FlowPanel or anything else - you can extend that and add sort() logic according to context. And override add() method accordingly. So, your first option looks like a possible solution to me.
