Zoom around the current mouse position is done like this: a) Calculate the zoom factor from the mouse wheel event. Notice it can be greater or less than one. Multiply the factor for the current window/rectangle/block/whatever sizes. Now you have new horizontal/vertical sizes. b) Get current mouse po...

I agree with PB, the control you need is a wxGrid.

program runs on another Win10 machine with same build number (different video card and motherboard This would point to a video driver mess. Try unistalling AMD (ATI) driver. Does it run with defautl Windows driver?. Clean the Win register, reinstall AMD driver and try again. *cube sample runs *pyra...

There has been some recent bug fixes in sizing some controls under GTK+3. Download the last code directly from "git" and recompile wx.

mwxString[0].GetValue() == "(" This is wrong. You're trying to compare a string (that inside "") with a wxUniCharRef (returned by GetValue()). More at https://docs.wxwidgets.org/trunk/classwx_string.html "Traps for the unwary" Use ' instead of " mwxString[0].GetValue() == '(' While your code is "ev...

wxWindow can receive keyboard input, as wxTextCtrl does. See the keyboard sample. You can have a wxWindow (or one of its derivates) and handle its char-events. Joining chars you get the string. Also handle paste-event, you can get a string in just one event. But you have to draw the text on your own...

As @doublemax told, the "double buffer" feature is provided by the OS, not glut needed. wxWidgtes allows you to set it, please read every class doc from this grup: https://docs.wxwidgets.org/trunk/group__group__class__gl.html Some more info in this post: https://forums.wxwidgets.org/viewtopic.php?f=...

Fixed two months ago.

Can you test it (as the patch uses gtk_widget_get_scale_factor() instead of gdk_monitor_get_scale_factor())?

In that ticket #17391 you can read that OpenGL knows nothing about the scale of the display. The best way to go is also told there: use const wxSize sizeInPixels = GetClientSize() * GetContentScaleFactor(); . No need to use GDK_SCALE , which will affect also the normal GUI. Then use that sizeInPixel...

Any GetXXXX function pass some value to your variable; the other direction is SetXXXX. To draw something that fits into a rectangle you first need to know the dimensions of that rectangle. The dimensions (width, height) of the "available" part of a window (the client area, without toolbars, menus, c...

Some comments, just to set it clear. The best way to do wxGLCanvas update is to have a wxPaintEvent handler (i.e. void OnPaint(wxPaintEvent& evt) ) in your wxGLCanvas class. This is what @doublemax is asking to be sure. This OnPaint() will be called automatically by the OS when it needs the window t...

Tell the sizer how to align the buttons using some flag of https://docs.wxwidgets.org/trunk/classwx_sizer.html#wxsizer_flags pSizer_0_0->Add(new wxButton(this, wxID_OK, L"AAA"), 0, wxALIGN_RIGHT); pSizer_0_0->Add(new wxButton(this, wxID_CANCEL, L"BBB"),1, wxALIGN_RIGHT); Notice the "0" I added to th...

Case 1 The task blocks everything, GUI included, until it's completed. Then code normally. No threads, no message-handling etc. This approach may only be user-friendly if the task finishes in less than a second. Case 2 The task blocks nothing. There are several ways. For example you may call wxYiel...

What wxWidgets can do about OpenGL can be read in the FAQ of "General Development", https://forums.wxwidgets.org/viewtopic.php?f=27&t=45552 there is an attribute to set up the stencil buffer size True.
