Menu
I can't get tooltip to work with my always on top window. Obviously the problem is you can't create something on top of something that's always on top; so i was wondering if there was a workaround or solution. The Popup needs to be always on top of other windows, but i also need to have all the tooltips show up properly.
Here's a stripped down version of what I have so far:
from Tkinter import *
class GUI:
def __init__(self, root):
Popup = Toplevel(root)
Popup.resizable(0,0)
Popup.attributes("-toolwindow", 1)
Popup.wm_attributes("-topmost", 1)
PFrame = Frame(Popup)
self.B = Button(PFrame, width=10,height=10)
self.B.pack()
self.createToolTip(self.B,"Click this button.")
PFrame.pack()
class ToolTip(object):
def __init__(self, widget):
self.widget = widget
self.tipwindow = None
self.id = None
self.x = self.y = 0
def showtip(self, text):
self.text = text
if self.tipwindow or not self.text: return
x,y,cx,cy = self.widget.bbox("insert")
x = x + self.widget.winfo_rootx() +15
y = y + cy + self.widget.winfo_rooty() +65
self.tipwindow = tw = Toplevel(self.widget)
tw.wm_overrideredirect(1)
tw.wm_geometry("+%d+%d"%(x,y))
label = Label(tw, text=self.text, justify=LEFT)
label.pack(ipadx=1)
def hidetip(self):
tw = self.tipwindow
self.tipwindow = None
if tw: tw.destroy()
def createToolTip(self,widget,text):
toolTip = self.ToolTip(widget)
def enter(event): self.tt = root.after(1500,show,event)
def show(event): toolTip.showtip(text)
def leave(event):
if self.tt: root.after_cancel(self.tt)
toolTip.hidetip()
widget.bind('<Enter>', enter)
widget.bind('<Leave>', leave)
if __name__ == '__main__':
root = Tk()
App = GUI(root)
root.mainloop()

Tooltips are useful in applications where we need to display some information while hovering on a button. In order to create and display a tooltip, we can use the Balloon property of tkinter.
The title in tkinter refers to a name assigned to the application window. It is mostly found on the top of the application. For this, we can use the title() function. We create a widget object using the Tk() function and use the title() function to add a title to this window.
config is used to access an object's attributes after its initialisation. For example, here, you define. l = Label(root, bg="ivory", fg="darkgreen") but then you want to set its text attribute, so you use config : l.
You can add a tooltip by calling . setToolTip("text") on a widget. This is often used to assist the user.
I fixed it by adding tw.wm_attributes("-topmost", 1) to the showtip function. Let me know if this solution is incorrect or if there is a better way.
