how to convert this to Purebasic?

Code: Select all

@property(class, readonly, nullable, strong) NSCursor *currentSystemCursor;
it looks like the value returned is not constant, it seems to return the mouse coordinates as well.

Code: Select all

Debug CocoaMessage(0, 0, "NSCursor currentSystemCursor")

It's return an object NSCursor. Not mouse coordinates

This is the current system cursor. A cursor is a object

Maybe you want something completely different!?

P.S. Example with CanvasGadget and macOS cursors

just in your example, press the mouse button and without releasing move the cursor to the edge of the window, the cursor will change to arrows and remain so. And in theory, while the button was pressed, the cursor should not have changed, or, at least, when we went beyond the borders of the window, it would return to the "cursor closedhand"

For me, the cursor remains close to hand, even over the edge of the window.

Just tested with v5.73, v6.00, v6.01.
Hand remains closed when leaving the window.

Probably due to the OS. With me macOS Ventura v13.0.1

I have tested mk-soft's last code example on my iMac 2019 with MacOS 11.7.4' Big Sur' with PB 5.73 and PB 6.00 (Asm and C backend). In all tests the cursor is an open hand cursor when inside the window and changes to an arrow when over the titlebar or statusbar and when leaving the window. After returning into the window the cursor changes back to the open hand image.

When keeping the left mouse button pressed, the cursor changes to a closed hand cursor. When keeping the mouse button pressed while leaving the window, the cursor changes to an image with a connected left and right arrow. When returning the cursor to the window, the open hand or closed hand (when still keeping the mouse button pressed) is reinstated.

@mestnyi,
in which environment do you code? On a real Mac, a Hackintosh or a PC or Mac with VM (Virtual Box, VMware, Parallels, ...)?

MacBook Air (13-inch, Mid 2013) 1.3 GHz dual-core Intel Core i5 processor
Shardik Sometimes when the cursor returns it is a closed hand, but in most cases it remains an arrow cursor.
I wonder what it could be related to?

Я думаю, что это ошибка Macos или PureBasic, так как при уже нажатой кнопке курсор в окне не должен был измениться.
