city/place. I have a toolbar which contains 'zoom in'
and 'zoom out' buttons. When the user clicks on zoom

on any part of the map. The map will refresh automatically

Greetings!
I am creating a form that will contain information that will eventually be
on a label. The label has a 2-column table with lines separating the cells.
I want my form to resemble the label, so I want to draw a rectangle and
lines on my form. I don't want them to have any user interaction whatever.
They would be there just to look pretty.
There's plenty of support for drawing rectangles from code. There seems to
be support...

Hi, how can i draw a rounded rectange, with a border within a specified
area?
i.e. if i have a Rectangle with width and height of 100, how can i draw
a rectange with 2 pixel border inside of the original one? (the current
attempts all draw the border just outside of the original rectangle).
At the moment im using the following code, but it allows the rectangle
to grow - which i definately dont want!

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
