I am new to wxWidgets. I have checked a couple of tutorials and can write simple code to generate simple GUI in C++.
Sometimes I have problems when I try to find a specific widget, or just a kind of widget. Documentation has some images. For example, if I want a scroll bar, I can search for it and see a picture too. But often, I have a picture in mind of what I would like to find, but simply don't know how it is called, or what category I should search in. Or probably even more commonly, a widget that would solve some problem already exists, but I just don't know about it.
If there is some online source, where widgets are listed and structured in a logical way along with their images, to quickly find and identify them... I haven't found it.
How can I find widgets to use?
Unfortunately wxWidgets doesn't have anything like this currently. What I recommend is running the widgets sample and looking at the controls shown in it. It doesn't show all of them (there are separate samples for most of the more complex or more esoteric widgets), but it does show quite a few.

There might be something wrong with the way I search for things but here is my problem. I'm looking for a way to implement a custom editing tool within the properties tool window in the Visual Studio editor. I've been looking through several documentation references, and they all lead to the use of different assemblies, but I can't get anything to work the way that I want.
First of all, I tried using the UITypeEditor class, with the step-by-step tuto I found here : https://learn.microsoft.com/fr-fr/dotnet/api/system.drawing.design.uitypeeditor?view=net-5.0
The problem I faced was that it only seemed to be working with Winforms projects, and I'm trying to use this with a WPF project.
Afterwards, I tried following this tutorial, in order to create a project template : https://learn.microsoft.com/en-us/visualstudio/extensibility/creating-a-basic-project-system-part-1?view=vs-2019
This has led me to think that the methods used in the tutorial might have been either deprecated or improved with the used of AsyncPackages instead of ProjectPackages, and the appearance of the Microsoft.VisualStudio.Shell.Flavor assembly that seem to render useless the ProjectNode class (it doesn't even show up anymore, the method has been replaced with a void).
The last bit I tried exploring was the use of the ProjectSystem, as documented here : https://github.com/microsoft/VSProjectSystem
It was actually worse because I couldn't get it to work like I wanted, the project type I was creating could not register C# files and I wasn't able to add new classes (I might need to dig a bit deeper here but I don't know where to look).
So basically, I'm looking for help to extend the properties tool window, through an editor within the window, or a modal window opened by clicking on an ellipsis button in the properties window.
Thank you for reading this, if you have any info, I'm very interested.
I've actually found a thread leading to what I was trying to do here. This tutorial leads to a way to implement a customized editor, either inline, extended or in another dialog window. This was the thing I needed, and with a few tweaks I managed doing what I wanted.
I just started developing an MFC application for the first time and I'm hoping to get more familiar with the whole "controls" concept. I am using the dialog editor in visual studio and so far I was not able to find functionality to add a simple table/grid. It seems quite basic to me, but I can't even find reliable information on how to do it on the internet.
I am looking for something similar to Qt's QTableWidget, something that I can later program with variable amount of rows and columns tailored to my application's use cases.
Do you have any ideas how to do it?
I use CGridCtrl which is very powerful and does a lot of the legwork for you.
Sounds like you're after a List View Control, which is wrapped by MFC's CListCtrl class. The dialog editor will enable you to add one and set its properties.
I need make graph in graphic framework Qt. I use QGraphicView and QGraphicScene and make my graph by hand (add Recangles, late add line to display hierarchy of single elements). For you to get an idea, picture, what I think:
And my supervisor tell me, that it is inefective. Somebody had to do something similar before me. So I must look for some library or framework in Qt, which support graph like mine (see above) and support mouse tracking, because after click I need do some operation.
So I searched on Google for few days and only thing I find is QTreeView. It is what I need, but it's for directory structure and that's not what I imagined.
Please, know somebody something like QTreeView, but in graphical adaptation? Thanks for any help.
I have what seems like a simple task. I wrote a Windows application using C++. Now I need to add to it a capability to print forms -- nothing fancy, just plain text, with lines, tables, and simple graphics. Besides printing, a user needs to be able to preview on the screen all forms being printed.
Previously I was able to get away with this task by using an embedded Internet Explorer control and design all forms in HTML (which I like -- the HTML part.) But the problem comes with IE... hmm... I wish I had a nickel every time I heard that phrase :) Anyway, IE can print an HTML page but it does not provide any easy way for users of my software to customize page size, page margins, etc.
I spent a good deal of the last week trying to make IE Print Templates work with what I need ... but eventually failed. That stuff is very poorly documented and what I was able to do seems to randomly crash on me. So at this point I gave up on IE...
So my question to you -- is there a way to incorporate printing into my C++ program for the purposes like I described above?
If I remember correctly, printers have their own HDC, and you can draw on it. That'll work if have something simple. If you want to render HTML page using pure WinAPI, you're in big trouble.
I'd advise to abandon winapi and try GUI framework instead.
Qt 4(and 5, most likely) has text editor that can display rich text, layout engine for rich text, component that can display web pages. Read documentation a bit, and you will most likely find a way to render web page onto printer instead of screen. So far it looks like exactly what you would need.
Using Qt will add dependencies (20+ MB of DLLs for your project), but, IMO< it is a better idea than trying to use IE COM interfaces.
If you don't want to use Qt, you could try something like WebKIT, but I had some bad experiences with it, plus Qt might be just easier to use.
Additional info on printing: Printing with Qt.
Try searching for GDI, if you want to use win32 builtins.
Or use another toolkit like wxWidgets. Or consider writing to PDF with some library. Or let LaTeX do the heavy lifting - writing text files is easy. The LaTeX-way works as long as you don't want to modify your output depending on the layout (one Use-Case that doesn't work with LaTeX is the "balance" at the top/bottom of each page.)
Consider having your program generate XML files and using XSLT to render them into HTML.
By attaching stylesheets you will make it much easier to customize the presentation.
OK, so my Windows application involves a window that, among other things, has a list of objects in a pane. Each object has 8 boolean values that need to be determined — so I'd like a list of the objects, with eight columns of checkboxes after. I'm not using MFC, should that be relevant.
ListView looks the way I want it to, but apparently it doesn't accept checkboxes in SubItems (the LVS_EX_CHECKBOXES style only gives each row a checkbox on the left).
So what I need is some kind of alternative to ListView that does allow this. I've been looking, but nothing I've found seems to work.
I have seen reference to some DataGridView control, but I don't see that as an option in my Visual Studio 2010 "toolbox" — how does one access it, is it even available for non-MFC C++ projects? Most references to it seem to be for VB or C#.
Another thing I found is is this custom ListView, but it, again, seems to be for C# and not C++. I'd certainly accept suggestions on how to use this resource in my code, if there's a simple way to interface with the C# dialogue (I'm completely unfamiliar with C#).
Anyway, any thoughts, suggestions, or tips anyone has, would be most appreciated!
EDIT: This should maybe go in a new question, but it doesn't really seem deserving an entire question on its own: MFC seems to have more support for this kind of thing (insofar as most of the custom controls I can find to download are for MFC). My project does not actually require being non-MFC, it just is, at the moment. How much work am I looking at to convert it?
Well, I've taken the plunge and started using MFC; the CGridCtrl I downloaded seems to be working pretty well, though I still have a lot of work on it. I'm going to call this the answer, then, since there doesn't seem to be another forthcoming.
