I have two questions.
1) I am attempting to arrange my objects in the Source Analyzer view into some kind of organized format on display so that i can sort through it. However, the Source analyzer option to "Arrange All" is "greyed" out when i go to the layout control panel.
Is there any way to arrange or organize the objects?
2) While the objects in my source are organized by the DB i import from, there is no such organized view in navigator for the Targets. All the targets are just dumped into the navigator! Is there any way for me to organize the view of the tables in the Target folder in navigator?
I cannot find answers for these specific questions online, so apologies if they seem basic. Thanks for your help fellow devs!
You can only arrange them manually.
The options Arrange All and Arrange All Iconic can be used only for mapplets and mappings.

So I am tasked with organizing possibly hundreds of CT scans for my uni project. The CT scan files will have varying degrees of different properties that we will manually assign and the idea is to simplify the process of finding appropriate files with specified properties quickly and accurately. The proposed idea was to just maintain an excel file for manual lookup.
But I am thinking of making a very simple windows app with sliders and checkboxes that will scour the entire file tree with nested folders and show the correct files in the app window that then could be drag and dropped and such. The solution has to be user friendly so barebones script-based solution won't do.
From the little research I have done, I have come across some corporate-based solutions for automated document classification. And there isn't really a comprehensive solution to having custom persistent file metadata, which is what I had in mind. Maybe maintaining some kind of lookup table for the application is the better way.
Is there anyone experienced who could steer me in the right direction and give me some advice and pointers? Or am I better off going with some other already existing solution? Currently my CS knowledge is very theoretical and I haven't really messed around with windows app development. Thanks in advance
I am looking for a simple way to create geographical maps in Django, in which I could then select, highlight and annotate countries or groups thereof.
"Annotate": insert a label displaying textual information about the said country.
Is there anything that comes to mind?
Many thanks
EDIT: I checked GeoDjango already and it looks like much work in order to get where I need to. Don't get me wrong: I'm not trying to minimize my own investment in learning new tools, but for this project, I have a trade-off between time allocated to learning and the relative importance of this geographical feature in my app. It's more of a nice-to-have feature I'd like to add to an already 'complete' app. So I wondered whether there exists a 'simpler' python library for this task.
I think this is more of a question for if there is a front-end library to elegantly handle this. However if you need to generate the maps you could try something like this
https://kartograph.org/
I have personally used this http://jvectormap.com/ and found it to be really good.
In your database you could just have a Countries model with any associated information you might need to display, and create a view to handle that appropriately.
I've started to work on a quite big C++ project. I've used BOUML to import the code base with the intention to create a visual UML diagram.
Now I've reversed the project and I see the classes, namespaces, methods and such in the project browser but I can't figure out how to create a graphical UMl from it, may anyone here help me?
Manually draggign the elements from the browser into the main area doesn't seem to be allowed as the cursor gets a forbidden icon and dropping the elments doesn't do anything then... how do I even create the UML myself?
muszeo2 is right, the reverse create the packages / views / artifacts and classes and their members, after you have to create the diagrams by yourself. Sorry but BoUML is not extra lucid and it cannot by itself create the right diagrams of the right kind containing the right elements with the right drawing options ;-) So create your diagrams and drag&drop the elements you want to show etc, they are several features helping you to make diagrams with elements already created or not.
I also made some video tutorials available on https://www.bouml.fr/documentation.html, I encourage you to look at them, starting by starting.wmv then cpp_example.wmv for instance, but you can also look at the others because the rules are quite identicals. These video tutorials are old and many features was added since I made them, but this is a good start.
You cannot drag&drop from browser to no where (I mean not into an opened diagram) nor when the element cannot be added in a diagram
we're maintaining some Qt applications which are running on Linux and Windows desktops. Now, we want to make the applications more attractive by adding customized forms and reports for each customer or at least groups of customers. There may be 10 or more different versions needed.
As we come from Qt, we are wondering how to manage so many configurations and if there already is a framework/development system that would help us here. We were looking at QML/Qt Quick, WT Toolkit or even NC Reports for the reporting part.
Managing configurations and deriving different versions from a base is not a feature which is discussed or promoted.
There should be a clean distinction between Display and Application Logic (Model/View)
Nice would be a textual GUI description, which enables us to release changes in forms or reports without the need to reinstall the whole applications (like QML seems to have that)
Also nice would be a kind of report generator, that helps to create forms and reports for new customers without the need to code them (and so releases our core developers from boring work)
Has somebody experience with such kind of customer based configurations? It would be nice to have a hint what's the best way to do this in the Qt surrounding.
I know comparisons like http://qt-project.org/doc/qt-5.1/qtdoc/topics-ui.html#comparison, but the specific questions that I have are not mentioned.
best regards
I guess you need to differentiate applications in three aspects:
1. appearance - if the application only differs in button color, icon image and background themes, qt's style sheet is light and convenient, you can choose to deploy different qss file and load different ones without recoding. if the variance among customers concerns layouts or available widgets (some has buttons, some use combo boxes, .etc), style sheet cannot meet the requirement, QML seems promising in such case.
business logic - i'm not sure how "generating reports" differs for different customers, if the reports need to be printed, or saved as document, i don't think qt provides good toolkit (QXXXDocument is not suitable to generate / display large amount of document), html? maybe. And i agree with #hyde that loading different plugins or dynamic libraries can solve this.
What I learnt from 8 month qt:
Model/View Architecture is there, for example a tree view that we fill with voyage data. the data is gatheres from several db tables, so we have a good logical distinction.
We hadn't the time to work us into qml, so we stuck with qt designer. It's quite easy, so we're fine with that. Delivering changes in customer forms without recompile will be a feature for a bigger future rework.
Same with report generators...
I am not fluent in UML, but I would like to create a class diagram based on existing C++ code. Other StackOverflow questions have indicated that two programs - Enterprise Architect and Rational Software Architect - are fairly good at "reverse engineering" C++ code (i.e., creating UML class diagrams based on existing C++ code).
I have downloaded the trial version for both of these applications. However, I cannot make any headway into understanding what to do to create a class diagram in either of these applications.
In Rational Software Architect, I have created a UML project, but I cannot find any way within the program to select, and reverse engineer, my existing C++ code.
In Enterprise Architect, I was able to import my C++ code, but all the elements (classes) appeared in a useless, overlapping diagonal line within the diagram. I attempted other settings, such as circle, but these were equally impossible to read because the diagrams were so large (due to the attributes and methods taking up alot of space) that no amount of panning and zooming was useful. What I would like is to hide everything except the class names (i.e., not display any methods or attributes) so that all 20 classes appear conveniently and legibly in one screen.
However, I am unable to find a way to hide everything except the class names. Rather, when I found an option (in Enterprise Architect) that seemed like it might hide everything but the class names, for some reason the elements all vanished in the class diagram, and no amount of repeating the steps & deleting and re-adding packages made the class diagram reappear.
Note: My C++ code (at least those files I selected for import into Enterprise Architect) amount to only about 20 classes.
Sadly, a very careful search of the documentation for both of these programs provides only generalities - no specific instructions are given regarding reverse engineering for either of these programs, so far as I could find.
I would be grateful if someone could tell me the basic steps to create a legible, easy-to-navigate diagram via. reverse engineering (i.e., C++-to-UML) that shows only the class names, so that about 20 classes fit (legibly) on one screen, using either Enterprise Architect, or Rational Software Architect - OR any other tool whatsoever that is capable of doing this (I suggest EA and Rational only because they have been highlighted in other StackOverflow answers as the best programs available for this purpose).
This answer applies to EA.
You can import individual files or whole directories, recursively or no. Directory import is by far the most common case; single file import does not allow you to create a diagram automatically.
When you import a source directory, you have the option of creating diagrams for each UML package, or no diagrams at all. You also decide whether to create packages for each source code directory, namespace (default) or file.
If your code constists of only 20 classes then it's likely they're in a single directory and/or namespace, so play around with that option (Package Structure in the Import Source dialog) to get the right number of diagrams.
In the same dialog, there's a button "New Diagram Options," which opens another config dialog where you can choose whether the diagrams should contain the classes' attributes and/or operations. You can also make the decision on a visibility basis, eg show public members only.
This dialog only affects what's shown in the diagrams when they are created. The members are still imported, just not displayed. This sounds like what you're after.
You can change the display options for any diagram by double-clicking an empty area of it, or right-clicking and selecting Properties. It sounds like you got into this dialog and changed something around, but I can't really tell what. The situation you describe, where you can't get the display back the way it was, is not one I've ever encountered in EA.
It is also possible to select display options on a per-class basis by right-clicking it in the diagram and selecting Feature Visibility. I don't recommend you use this in reverse-engineered diagrams, I'm just mentioning it for completeness.
The layout you describe, with all classes in a meaningless diagonal, suggests to me that the diagram isn't being laid out properly after creation. The diagram creation is a two-step process; first all the classes are dropped onto it, then the layout is applied.
This is strange, as EA automatically lays out generated diagrams and I haven't been able to find an option which allows you to deselect this behaviour. If this persists, send a bug report to Sparx Systems. You can always lay out the diagram by opening it and selecting Layout Diagram from the top-level Diagram menu.
If, finally, your classes are spread out among different packages and namespaces so that EA generates multiple diagrams for them, you'll have to merge them manually. Do this by opening both diagrams, selecting all (Ctrl-A) in one, copying (Ctrl-C) and pasting (Ctrl-V) into the other, then ask EA to Layout Diagram again.
So:
Right-click an empty package in the project browser, select Code Engineering - Import Source Directory.
In the dialog, select the root directory and source type.
Tick "Create Logical Diagram for Each Package" and select the Package Structure which best fits your source structure.
Click "New Diagram Options" and in the new dialog untick "Show Attributes," "Show Operations" and "Show Property Methods" if applicable.
OK both dialogs.
If multiple diagrams have been created, copy all classes into a single diagram.
If the layout looks bad, select Diagram - Layout Diagram.
Hope this helps.
