Hi!
This is a repost from the r/godot subreddit, but noone could help me there, so I’m trying my luck here.
I have a HBoxContainer with a placeholder circle (using a TextureRect) and a button. I want the circle to be visible the whole time, but the button should be hidden. When I hover over the circle, the button should be revealed and I should be able to freely interact with it. When the mouse leaves both the button and circle, the button should be hidden again.
So, I used the mouse_entered() signal of the circle to reveal the button, and the mouse_exited() signal of the HBoxContainer to hide it again.
But when I run it, the button shows up when I hover the circle, but also dissapears when I leave the circle. I also tried changing the Mouse Mode of the Button to “Pass”, but that didn’t help. How could I fix this?
The problem here is that when the mouse Enters the child control, that causes it to Exit the parent container. There are probably a number of ways to handle this “manually”, but here’s one that seems to work.
First, my test scene looks like this:
Control
HBoxContainer
TextureRect
Button
Next, the Button control’s mouse_filter must be set to pass
Finally, I have the following script attached to the Control node.
extends Control
@onready var hbox = $HBoxContainer
@onready var button = $HBoxContainer/Button
# Called when the node enters the scene tree for the first time.
func _ready():
button.visible = false
func _on_texture_rect_mouse_entered():
button.visible = true
func _on_h_box_container_mouse_exited():
if not Rect2(hbox.get_global_rect()).has_point(get_global_mouse_position()):
button.visible = false
func _on_button_pressed():
print("Button pressed")
Of course, you’ll have to season to taste if your scene structure differs.
Hi!
Thanks, that worked! Though I have one question: I understand what “get_rect()” does, but what is “get_global_rect()”? I don’t quite understand the difference.

get_rect() and get_global_rect() are similar - they just return the rect info in (potentially) different coordinate systems. I’m using get_global_rect() as it should coincide with the coordinates returned by the get_global_mouse_position() call that we’re comparing.
You can see the detailed difference between the two methods here:
