C++ GUI Programming For Beginners | Episode 2 - Creating a Window

Learn how to program cross platform graphical user interfaces in C++ using wxWidgets.

This time we begin programming GUIs by creating a simple application which displays a window on the screen (with a title!). We explore the absolute basics of wxWidgets and start to get a feel for the library.

We need wxwidgets tutorials man, please don't stop posting, you know that the resources to learn wxwidgets are limited

[seanhauth]

These videos are amazing! they have been helping me greatly so far! i look forward to watching the rest of these videos to study along with! you make it very understandable to someone who is new to programming like me! thank you and i look forward to more C++ tutorials!

Can you tell me fix for blurry text on higher resolution screens in wxwidgets. I tried to fix it using manifest file and it worked, but is it only way of doing it ?

[DarkValley-bp]

I have a question. In 2:05, why did we include the <wx/wx.h> library in the implementation file if we have already included it in the header file? Can’t the compiler or preprocessor or whatever just include the library of <wx/wx.h> from the header file?

So when I am trying to create the App class, I get a notification saying class not registered. I tried looking up to see what it meant or what i can do to fix it and it gives me a lot of different options. Do you know what is causing this?

Hello! With the code at 6:19 I am getting the following error: 'wxTopLevelWindowMSW::Show' not accessible because 'mainFrame' uses 'private' to inherit from 'wxFrame'. Am I doing something wrong? I have the exact same code as shown in the video.

Thank you very much for this introduction video! I still need to figure out all the class-related topics in c++ to fully appreciate what you show in your video, but this is just super cool!!

[ucTran-rycv]

I aways watch your video, i dont good with my english, but you are my source of motivation, thank you very much

[yousefibrahim]

I appreciate this thorough tutorial, keep it up!

[Mako-wl]

humans plese help me i press "start" my program is start but my start dont visible on down panel

[chiefbromden]

What about calling destructor? You created dynamically one object mainFrame by using the new operator. Is there any garbage collector in the wxWidgets that does this instead of you?

[kazuakane]

I have some trouble in the Mainframe keep telling no instance of overloaded function

[СергейСергей-ччй]

Is there memory leak of mainFrame after exit of OnInit?

[mariosvasiliou]

my project is built without errors. However the window doesn't appear on the screen. Any idea? Thanks

[ttariq]

There is no error but my window is not getting appeared just the program runs and nothing happens

[rockshoxx]

I'm getting a weird error saying "link.exe" exited with code 1168 and how it cannot open FirstGUI.exe for writing, Any solutions to this?

[dimasbaskara]

hello! I like this video, but why when I started debugging, it keeps showing unable to start program the system cannot find the file specified. why this happened? Thanks in advance!

[glados]

Great video! I'm trying to run your code on linux, but I keep getting this error:
App.cpp:(.text+0xea): undefined reference to const&)'
collect2: error: ld returned 1 exit status
Any ideas why?

[iCrazy]

I'm running no errors, the only thing I changed was changing the name of the .h and .cpp from App to App1 since I was running into an error "class not registered". It compiles just fine but the GUI is not popping up. What's going on?
