How to enable window resizing?

I would like to be able to drag the corner of the game window to resize the window. I have enabled Allow Window Resize in the project settings. However, when I put my mouse cursor near any window border, it flashes the resize cursor before instantly reverting back to the regular mouse cursor.

I am enabling the cursor to be visible in the first place using bShowMouseCursor in APlayerController.

Use this nodes to enable border mode:

Thank you for the help. These nodes do work to set windowed mode, but I still cannot resize the window with click-and-drag.

(i.e. my cursor does not change to

, and I can’t drag the sides of the window to resize)

It turns out that this is a bug: Unreal Engine Issues and Bug Tracker (UE-80522)

Nice, just discovered this myself. My program is analytical in nature so full screen mode will probably not be desired and resizing it should be easy for the user.

I’m encountering this issue in UE 5.6, both in a packaged build (.exe of windows) and Standalone Game in Editor.

The behavior is as follows:

  • When the mouse cursor approaches a window border, sometimes the resize arrow briefly appears and then disappears; in other cases, the arrow doesn’t appear at all.
  • However, if the cursor is placed in a some good position near the border, it’s possible to initiate resizing by dragging, even if the arrow icon never appears.
  • Once resizing actually begins, the arrow cursor displays normally during the drag (as expected for a standard Windows application).
  • I found it easier if I position the cursor near the top edge of the application’s title bar. That way, even if the click misses slightly, it’s easier to retry the drag.

If anyone has a reliable workaround, I’d appreciate hearing about it.
