Here is a simplified example of my problem:
I want to make the edit box 1 or 2 visible, depending on whether a checkbox of box 1 or box 2 is checked. The variables "variableCheckbox1" and "variableCheckbox2" are connected to the respective ceckboxes.
I have written a function as shown in the picture. The function is called from the EditBox 1 ("Enabled"). This is a possible solution for ONE box each.
Does anyone have an idea if there is a more elegant way to do this for a very high number of checkboxes / edit boxes?
A possible solution would be to write a function with a switch case for each variable in my model, called from each box. A very inelegant solution would be to make a single function for each box, but I don't consider that a good way.
If you want this for a large number, turn the entire setup into its own agent type: Checkbox and editbox. Instantiate as needed, you can add a parameter to specify what this is about exactly...
This would be the most generic and powerful approach...
if this works for you, you can use replications for checkboxes and editboxes and associate them together through the index... and then just add the code in the visible field of the edit box... Of course you will have to determine their positions programatically

I want to know if it's possible to make first two lines (Titles and horizontal line in the image below) always show on top and to be unclickable, to make them something like a header of the current listbox.
I think that your approach is not feasible since this is just not how listboxes work (i.e. it's not a spreadsheet where you fix the top rows). Having said that, you might be able to create something that looks like what you're suggesting, by creating two listboxes one below the other, making the top one read-only or non-interactable (or better yet, make the top one a static text label or a text area).
Another thing I'd like to comment about is the structure of your listbox. In terms of UX, it's uncommon for a user to choose two things at the same time. So even if this makes sense in your context, I would advise to split it into two lists, and have them change each other within callbacks.
So, I'm pretty new with Anylogic, but have done a lot of tutorials and I have programming experience in Java. For my thesis I'm modelling a vehicle flow as a process. In the source block, I create custom agents (vehicles) with some parameters from the database. This works fine. Then I want to assign an electric parameter with randomTrue(0.5). For this, I call a setupTaxi-function, where electric ist set. The parameter for the randomTrue-function should be changeable, so I set it as an extra paramter anteilEtaxis (0.5).
After that, I want the vehicles to do different things depending on the value of electric using SelectOutput. I selected the Condition and test on agent.electric.
I basically did the exact same thing as described in the Anylogic help. And yet the framework always chooses the true Output port, no matter if the parameter ist set to true or false.
See the image for setup and parameters. I tested this via console (the first line is a println-call in source, the second a println-call in selectOutput.). Plus you can see that the parameter is set to different values, because the 3D visualisation model depends on it:
enter image description here
Also, I tried a few different combinations of setting the parameters, reading them etc... The only thing that will work is putting randomTrue(0.5) directly in the Condition box. This is not what I want though. So if you have an idea, what is wrong, please tell me.
This is a typical beginners problem.
I will assume you are calling the setupTaxi-function in your source in the "on exit" action... If you are doing that, then it's too late and the agent already made its decision on where it will go after the select output block.
You have to call your setupTaxi-function in 2 possible places:
1) In your source on the "on at exit" action
2) In your vehicle agent on the "on startup" action
Or even.. just make electric variable have a default value of randomTrue(main.anteilEtaxis)... that will also work.
I'm using the VLOOKUP function to move data from one table into another. I need to apply this formula to an entire column, and I need to know how to define certain parameters as variable and some as constant.
Here's my problem:
=VLOOKUP($D8,Sheet2.A1:B20,2)
becomes, when I drag the corner of the cell across multiple rows,
=VLOOKUP($D8,Sheet2.A1:B20,2)
=VLOOKUP($D9,Sheet2.A2:B21,2)
=VLOOKUP($D10,Sheet2.A3:B22,2)
=VLOOKUP($D11,Sheet2.A4:B23,2)
And what I need is
=VLOOKUP($D8,Sheet2.A1:B20,2)
=VLOOKUP($D9,Sheet2.A1:B20,2)
=VLOOKUP($D10,Sheet2.A1:B20,2)
=VLOOKUP($D11,Sheet2.A1:B20,2)
With the first parameter changing and the rest remaining constant. I'm sure there is an easy way to do this, but searching and browsing help topics is returning nothing. I admittedly have zero background in spreadsheets. Thanks for your help
Add more $ signs, like this:
=VLOOKUP($D8,Sheet2.$A$1:$B$20,2)

I am using Behavior Search to calibrate my NetLogo model for 20 different hospital units. I am using global variables to set the min and max for several sliders in my model, but I think this is causing an error in Behavior Search when I attempt to load the parameter values from the model. However, I don't want to manually enter these parameter ranges manually each time I use Behavior Search.
Is there a way to get around this error? Is there a way to set the min and max for a specific slider to a constant, rather than using global variables?
Thanks for your help!
BehaviorSearch developer here -- if I'm understanding your question correctly, your NetLogo model has a slider which has a min/max constraint that is not set to a constant, but is instead set to a global variable (in the slider settings, accessed from the NetLogo interface).
When I choose such a model using the BehaviorSearch GUI, and then click the "Load parameter ranges from model interface" button, then I get the value of 0 for that constraint. (I don't see any error message -- just the value 0 (if you're getting an error message instead, then I may not be understanding your situation correctly, and perhaps you could post exactly what error message you're seeing?)
This will be true even if you are setting the slider min/max to a global value in the special STARTUP procedure (see: http://ccl.northwestern.edu/netlogo/docs/dict/startup.html), because STARTUP is only run when a model loads in the NetLogo GUI, and not when a model is loaded in headless NetLogo.
Thus, unfortunately, I think the answer to your question is: "no, there isn't a way to get BehaviorSearch to load the parameter ranges from global variables within the model".
Some possible work-arounds:
BehaviorSearch is open-source -- some changes could be made to it -- i.e., maybe adding in a call to "startup" whenever BehaviorSearch GUI loads the parameter ranges would be sufficient for you.
If you're only doing a few searches, I don't see why manually editing the parameter ranges would be particularly onerous. However, if you're generating a lot of different searches with this model, then I can see how it might be an issue. The .bsearch files are just XML text files, so you might consider generating them without the BehaviorSearch GUI, e.g. using a scripting language.
I have a custom node type for which I want to have a field that uses a special combobox based on list_text. When one chooses the type list_text it is normally possible to enter a static list of selectable texts, however, I want this list to be dynamic, i.e. based on the results of a db_query. What is the best way to do this using Drupal 7?
A simple example for clarification: A node of this custom type X contains a field that points to another node, so whenever a node of type X is created I want a combobox that contains all other nodes.
(Best solution would be to only display the combobox during node creation, and no longer during edit. But I could also live with it if the combobox was shown during the edit as well.)
I have tried to customize options_select by defining my own data type and implementing hook_options_list accordingly. The combobox was displayed during creation with the correct values, however, I could not save it.. I have no idea what went wrong there, but on the first submit it would change to a different theme, and when I tried again I got an internal server error. Am I on the right track at all with defining a completely new data type for the field? there surely must be a simpler way?
You're right in that you don't need a new datatype. Here's a good tutorial on how to do this. It's not specifically for D7 but I didn't see much that wasn't still applicable. There may be a better way to do it in D7 specifically but I would love to know it too if so :)
The tutorial linked by allegroconmolto sent me on the right way. Thanks for that.
Here's the simpler way of doing it: tutorial
Basically, it is, as I assumed, a common problem and hence a simple solution for it was included in the webform module by now. It provides a hook_webform_select_options_info which can be used to register a callback method. The callback method is then called each time a corresponding option select of a webform is shown, so that you can easily fill it with the results of a dbquery or anything else. Works like a charm and takes next to no time to implement.
