SDL Version: SDL-2.0.4 build 9783
OS: Windows 10
Monitor 1: 1920 x 1080
Monitor 2: 2840 x 2160 (configured to the left)

While using SDL_SetWindowHitTest on a window to control dragging of a custom caption bar, the hit test functions correctly while the window is on my main monitor. When I drag the window and drop it on my second monitor it reports the x mouse position in the hit test as around 65500 for the top left of the application where it should be 0. Y position functions as it should set as 0 for the top left.

I'm not sure if this is a problem since I am using the latest build of SDL or not, or since I am using a 4k or windows 10.

What are you expecting for the x position? The left desktop is negative in windows.

Subject: [SDL] Window Hit test reports wrong x position

SDL Version: SDL-2.0.4 build 9783
OS: Windows 10
Monitor 1: 1920 x 1080
Monitor 2: 2840 x 2160 (configured to the left)

While using SDL_SetWindowHitTest on a window to control dragging of a custom caption bar, the hit test functions correctly while the window is on my main monitor. When I drag the window and drop it on my second monitor it reports the x mouse position in the hit test as around 65500 for the top left of the application where it should be 0. Y position functions as it should set as 0 for the top left.

I'm not sure if this is a problem since I am using the latest build of SDL or not, or since I am using a 4k or windows 10.

I'm not looking to get the window position, this is the internal starting position( I should have clarified that sorry)
On the main monitor top left of the application reports x = 0, y = 0, On my left monitor my top left of the application is x = 65500, y = 0
I have just tried it with 1920 x 1080 and it still reports the same problem with x.

If I place the monitor on the right it will behave as expected and give x = 0, y = 0 as my top left in the application.

I just tried it in other positions and have found that if i place it above or below the main monitor it will only give correct 0,0 if the 2nd monitor is equal to or greater than the X position of my main monitor, anything below will result in the top left of the application setting X to 65500

Example: http://puu.sh/iQx9q/10db29552b.png
In this my main monitor is Screen#2 and Screen#1 is my secondary. Any time I set the monitor below the original starting X position it will always report the X position as 65500 for the top left of my application.

Hopefully that explains it a little better.

This is likely an SDL bug, hit testing is all new code still. Can you
stick this in Bugzilla so I don't forget to fix it?

Thanks,

I don't have access to a second monitor at the moment, though I'm going to take a look and see if I notice anything... I'll update to the bug case as well...

Zelif, please pass along the issue/case # .
