I've been looking for solutions for several weeks now, but I'm having a bit of trouble finding and understanding (in cases where I find documentation).
I'm currently developing an application for a school project. But I used a GtkToolPalette (https://developer.gnome.org/gtk3/stable/GtkToolPalette.html) so that the user can have icons to drag and drop into a drawing area. The problem is that first of all, these icons are very specific to what I want, so I can't find them in the icons that Glade/GTK3 already offers. Second, if I add all the icons one by one in Glade via the buttons on my GtkToolPalette it creates images each time (i.e. a lot) in the hierarchy of my objects, widgets and it completely pollutes my Glade workspace.
Is there a way to make all these additions cleanly. At the moment, I haven't found any method via glade. However, I finally found this https://developer.gnome.org/ThemedIcons/ but I don't really understand the method.
Does anyone know of an effective method?
Thank you in advance for your attention and your answers :)

We need to get rid of DevExpress Bootstrap Controls for ASP.NET Core from project.
What would be the easiest/cheapest/feastet solution?
To simply rewrite everything with a different framework like Angular/Vue/React?
Maybe there is a known framework/method of migrating to DevExpress ASP.NET Core Controls? Or to something else?
How many controls were used from DevExpress?
If you only used a few controls, then you only need a few replacements.
I would not call purchase of some controls from DevExpress a whole "framework", but that of only purchasing some controls to use with your project.
So, does the project use 3-5 or 50 of those DevExpress controls? (by using, I mean DIFFERENT kinds of controls).
If you only used a few, say like their GridView, then you would only need to find a replacement for their gridview control, or simply use the built-in one, and fancy it up with some css, and addtional options. (I would make a user control).
So, you want to determine what the controls used did, how many different controls were used, and then find some controls that have a great look and feel that you like.
Their grid controls are VERY nice, since they have some "really" nice filter options for the header of that grid control.
So, you need to find some control replacements, but how many did the project use will quite much determine scope here.
So, in place of say their tab control, then consider using the jQuery one. As noted, I would wrap say the jQuery.UI tab control into a user control, so then you can just drag + drop in that jQuery.UI "tab" control in place of the devExpress one.
Same goes for the multi-select combo box (dropdown list).
So, either you cobbile together some replacements of your own, or you find some replacemetns, or you buy some more controls from another vendor.
The challenge and issue will of course be that each of their controls has a specific object and event model.
However, that's not really any different then say if you started used sweet-alert, and now want to replace sweet-alert say with some jQuery.UI dialogs.
I would say that the real challenge of replacing their controls is often not so much finding a replacement, but finding something that has a great look and feel. The main huge wonderful bonus of the devExpress controls tends to be their look and feel. In other words, they had someone with REALLY good taste in terms of look and feel.
I mean, for years I used the ajaxtoolkit. (free, open source). it was and still remains a fantastic set of controls. The pop dialog, the tab control, the multi-select combo box, the HTML editor?
They are all great, but their HUGE downside is not the features, but the controls from that free toolkit look like something from the 1980's!!!
The popular jQuery.UI? Same thing, the controls look ugly and something designed by a un-employed rodeo clown living in a trailer park.
There is a HUGE but BEYOND huge reason that bootstap is so popular.
Know the answer?
Why of course bootstrap is popular for ONE big HUGE massive SIMPLE reason:
Bootstrap has a fantastic look + feel. (zero other reasons for bootstrap being popular!!).
If you ever hired a graphic artist to re-work the look and feel of your web site? Guess what? Their resulting work and suggestions will look like the default of bootstrap!!!
So, someone in the print and graphic design industry or someone with VERY good talent and great taste created the bootstrap system. So, when you use bootstrap, then you get fantastic looking results, results that normally would take a full time graphic artist on your staff.
Regardless, we are wondering off topic here.
The main issue you have to determine is how many controls were used from devExpress. Most of their controls do follow a similar object model as the base controls found in asp.net webform controls.
So, for example, jQuery.UI controls has a great set of features (a great set of UI components), but they look way too dated and old fashioned.
The issue you have is not that you want to replace some of the devExpress controls you used, but how much work it would be to replace say a dev-express "gridview" with another different grid control. Every single one of those controls used will not only require you to spend HUGE amounts of time finding a replacement, but I think the LARGER issue is finding something that don't look like it was created by someone living in mom's basement, or by that drunken un-employed rodeo clown that does not belong in our industry.
your issue is not finding some replacement controls, your issue is how much code and money (time and resources) you have available to replace those controls.
You can no more change a bunch of code in c# to then using say client side JavaScript can then you take some Pascal code, and covert that code to vb.net code.
There no more a replacement for those controls from dev-express then there is deciding tomorrow to re-write some server side code in vb.net to now being client side JavaScript code.
In fact, what I am quite much telling you?
How the computer and IT industry has worked for 50+ years has NOT change one bit, and it not change one bit if you decide to rip out some existing controls and replace them with different controls.
Its possible you are asking for something you never seen, never heard of, and thus are imagining some magic wand here, but those don't exist in our industry either, do they?
As I noted, for quite some time, I used the AjaxToolKit. Turns out that jQuery.UI has near EVERY the same kind of controls available. But, the massive difference is jQuery.UI controls are client side ones, but worse yet, they don't work the same as the AjaxToolKit ones. In other words, there is a nice "tab" control in AjaxToolkit, and there is a nice tab control in jQuery.UI. So, they both are tab control, but THEY are VAST different in their operations, how you use them, how they work.
However, both the jQuery.UI and the AjaxToolkit tab control?
My gosh, do they look like crap.
At least the jQuery.UI one can be easy bootstrapped styled.
Again, note how we not really now back to a JUST having a control replacement, but one that looks VERY nice and VERY tasteful out of the box, and a control that should take zero efforts on your part to obtain that great look and feel.
Want to know what product has those great looking controls and great look and feel out of the box?
the DevExpress ones!!!
I am trying to create a new project with the new GUI BUilder (I've already made hand-coded project). I watched Steve Hannah's tutorial about creating a sign-in form. If the sign-in form was hand-coded then it would have to use eg a Y-BoxLayout Manager. However in the tutorial everything is laid-out without resorting explicitly to this layout manager what I understand because the designer provides the layout.
But I wonder why new the GUI Builder offers such containers with specific layout managers ? What are the use cases when they should be used, and are they meant to be used as is (as ready-to-use examples) or the designer should remove the components inside with custom ones ?
Thanks in advance for the shed lights ;-)
The current version (3.7.2 and earlier) works best with a flat layout (i.e. not nesting subcontainers). The next release will include improvements that make it easier to work with nested layouts.
There are many reasons why you might want to use a nested layout. A couple of use-cases that come to mind are:
If you're laying out a form that has more than one logical section and you want to be able to lay them out independently. In this case using a couple of sub-containers that both use LayeredLayout themselves can make things a little easier.
If the layout has a nested list (i.e. box-layout-y) that you will populate in code at runtime with content that you load from a web-service, etc..
I'm a complete novice in gui-programming and I'm looking for an easy way to visualize a data structure I have. I own another program that does a similar job and the component it uses seems like it would fulfill my purposes as well. So instead of testing out different components myself (Which would undoubtedly force me to learn a lot), I'm wondering if there's a fast way out of it.
Is there anyway to find out what specific wpf/winform component a program is using without asking author/having source code access?
Edit:
Looks like this, the area it's in is scrollable horizontally/vertically. The objects on it are selectable, moveable and have actions associated with their right-click menu. I want to visualize an undirected graph and have the possibility to interact with the nodes graphically.
Here's the control I'm talking about:
First step, I'd look at the assemblies the app references. If it references a dll from a component vendor (a simple search can figure this out), you can visit the vendor's website and check out their offerings.
If it is a custom control embedded within the application, and its a WPF app, I'd use Snoop.
(Image ganked from http://snoopwpf.codeplex.com/). Snoop can sniff out the visual tree of a WPF application at runtime and show you all the controls that make it up.
This is no standard control but some propritary one. You can have a look in the program folder of that program which dll's they use, chances are that you can use this dll in your own app. Note that the license of this application may forbid using the code!
Anyone know which control they used on this site to get the Organisation chart? http://www.yworks.com/products/yfilessilverlight/SilverChart.html
Or any other controls that are similiar?
If not, could you suggest a way on how to get started building one? (Interface-wise, I think I know how to get the data binding to work).
The organisation chart control is their own, thats whole point of the demo page.
The UI elements involved are quite simple rectangular items. The real trick is calculating their placement on panel and routing the connecting lines.
I guess the missing peice of the puzzle is what generically we would call that. If you know that then you have a basis for a web search for algorithms for doing this sort of thing either academically or in some other product entirely, then bring that knowledge to your own Silverlight code.
Alternatively you could just go out buy the product.
A while ago I created a drag-over check box list which allows you to check many check boxes in a single gesture. Do you think it is viable and usable on the web where people might not know how to use it. The default behaviour still works for the individual check boxes.
1 - The idea
The idea is nice and can probably be used in professional applications where you have direct contact with users and can explain them how things work, but not necessarily on public websites where users don't want to RTFM and are just looking for familiar behaviours. Unless it was just a sample exercise or a control meant to be included it in a control pack, it violates the YAGNI principle ;)
2 - The implementation
You certainly noticed that the implementation is buggy (at least on IE7 and FF3.1B2). Sometimes, a gesture above all checkboxes will select all of them but one or two. Moving the mouse over the div's above or below the list will stop the drag (I know it's a "feature", but it's not very user friendly). I Checked the source code and to be honnest, while it looks pretty neat, I just didn't want to deal with it because it is plain javascript. Don't you know that...
3 - Possible improvements
...you can write less and do more with a javascript library, typically jQuery. I would completely rewrite this control as a jQuery plugin. It will provide you with a lot of tools to make your code much easier to write, maintain and extend. Just try it, you'll love it. This is from a technical point of view. From a user point of view, try to make you control as familiar as possible, like what Angela suggested, windows explorer : a nice selection rectangle, the ability to use shit + click, or something like that. Finally, remember that for many windows checklistbox users, "selected" and "checked" are two different things.
The demo definitely needs a few enhancements to make it even a little bit useful (although I am not sure if it would be enough):
Allow the dragging to start somewhere that is not a check box.
Allow selection by dragging over the labels as well.
This problem seems similar to the action of selecting multiple files in a file explorer like Windows Explorer. Maybe it can work like the action of selecting multiple files by dragging a rectangle shape around the items to be selected (select one corner, drag to the other corner)? This has the advantage of being similar to an interface element that people may already be familiar with.
For some reason I can't open your link (it says my ip address was blocked). But I think what you're looking for is what I already did in jquery, I uploaded a plugin which I basically ported from crossbrowser.com's dragcheck functionality, it was to be found at http://plugins.jquery.com/project/dragCheck but currently the jquery plugin site is being revamped and my plugin has disappeared. I'm trying to see if they're going to put it back up or if I have to create a new project again...
Anyways until we get that worked out you can see a demo here: http://jsbin.com/ibihi
