Hi, The crash occur with wx 3.2.4 and GTK 3, right? What is the backtrack at that time? Can you try building as DEBUG and run it under gdb? I was hard to track down, but i got it: the crash occured only on the BBB, with wx3.2.4, no matter what GTK. It was an infinite loop of OnSize events, 'cause t...

If your code works, I wouldn't worry too much about GTK messages.

Thank you.

the final app crashes for a segmentation fault, so no, it does not works.

My project until now was compiled in a Debian PC, using GTK2 and the wxWidgets 3.1.2 Is that a standard debian x86_64, or on the Arm PC? If not on the Arm, I suggest trying building/running with GTK2/wx3.1.2 there. If that runs OK, it narrows down the possible causes. Sorry, i try to be more clear:...

I am in the (extremely painful) process of writing a Makefile in order to compile for linux-arm from a Windows PC, using a WSL Debian image. My project until now was compiled in a Debian PC, using GTK2 and the wxWidgets 3.1.2, now i want to switch to GTK3 and using the latest stable wx 3.2.4 I've al...

I confess my full ignorance about the GTK subject, i tried to read online but i hardly understand. Please be patient with me TL:DR Should i use GTK2 or GTK3 with wxWidgets? what would be the differences? Why i get the error Gtk-CRITICAL ** gtk_distribute_natural_allocation assertion 'extra_space = ...

Thanks to you both

oh ... i'm definitely dumb. It created a subfolder in the minimal one called gcc_mswud_MinGW1320x64_d and put the .exe there. Thanks a lot. Now, just to try to set it in my memory (or at least have it written here): seems to me that it wasn't that way the last time i tried... i remember the samples ...

What is "x86_64-w64-mingw32-g++" doing there were building only the samples? I don't know: It is the output i get after the mingw32-make minimal command. You need to pass the same build parameters to the samples you used for the library. [...] You should also use the same -CFG, otherwise ...

Seems that i always stumble on this step... sorry if the question is stupid but i didn't find a solution before asking here. I've downloaded the latest sources, and compiled with MinGW64 13.2, using this command: mingw32-make -j8 -f makefile.gcc setup_h CXXFLAGS="-std=gnu++17" USE_XRC=1 SH...

I assume under Window the Magnification API is used, which does all the heavy lifting: https://learn.microsoft.com/en-us/previous-versions/windows/desktop/magapi/magapi-intro I've stumbled on this page: https://blogs.windows.com/windowsdeveloper/2019/09/16/new-ways-to-do-screen-capture/ and other t...

I doubt it's possible with wxWidgets methods alone, you'll probably need some platform specific code. For a start, wxScreenDC is the only way to access the screen content, and i wouldn't know any way to exclude your own window from it. I assume under Window the Magnification API is used, which does...

I'm investigating if making a program similar to the Windows 10 Magnifier using wxWidgets is doable. The goal is to have a full-screen window which shows a zoomed portion of what is under the mouse, and that allows the user to click on what is shown. This makes me think immediatly at two problems: c...

I've learnt how to draw what i want using DC in the OnPaint event of a wx<something> (i usually derive my components from wxPanel).

I wonder if i can do the same drawing from OUTSIDE, so (as example) drawing a gradient from the main form on a child wxPanel.
There's a way do it?

Thanks a lot.

This is part of how my app is built: wxCrafterTree.png How can i get a wxGridBagSizer* to grbHelp_MAIN ? If i call m_Page_15_HELP->GetSizer() i get a pointer to boxSizer5409 ... There's a way to get it starting from m_panHelp_HOME ? It would be more handy as that hierarchy will never change, while t...
