Kivy on Raspberry: Cursor is outside of window



I am developing a GUI on my RaspberryPi 3 using Python3 and Kivy 1.11.0dev. The GUI is working, it is running in fullscreen after start (as far a I know since Kivy 1.9.x it is not possible to run a Kivy app as a window) and the mouse cursor is visible. The only problem now is that the user can move the mouse out of the visible area if he goes too far to the left, right, up or down. If this happens, it is difficult to get the cursor back to the visible area.



I tried a lot to prevent that or to take the cursor back to window automatically but without success. From similar posts I tried things like this:


Window.bind(on_cursor_leave=self.on_leave)

def on_leave(self, *args):
if self.hold:
print('Cursor leaved Window')
# call api calls here



I also tried to grab the mouse


Window.bind(grab_mouse=self.on_leave)



Does anybody have a solution for putting the cursor back to the visible area after leaving or to set a border where the cursor can't leave?

Makefile test if variable is not empty

Makefile test if variable is not empty In a makefile I'm trying to I've created this simplified makefile to demonstrate my problem. Neither make a or make b executes the body of the if, I don't understand why not. make a make b .PHONY: a b a: $(eval MY_VAR = $(shell echo whatever)) @echo MY_VAR is $(MY_VAR) $(info $(MY_VAR)) ifneq ($(strip $(MY_VAR)),) @echo "should be executed" endif @echo done b: $(eval MY_VAR = $(shell echo '')) @echo MY_VAR is $(MY_VAR) $(info $(MY_VAR)) ifneq ($(strip $(MY_VAR)),) @echo "should not be executed" endif @echo done I'm using $ make --version GNU Make 3.81 There are several problems, and misunderstandings. Your MY_VAR is a make variable, set it without a <tab> to its value, and no need to $(eval ...) . MY_VAR:=$(shell echo whatever) is enough. No <tab> before $(info ...) neither, this is make – Zelnes ...
