# 1. With wx.ListBox (And Probably Other Controls), The BalloonTip Sometimes
# Flashes (It Is Created And Suddenly Destroyed). I Don't Know What Is
# Happening. Probably I Don't Handle Correctly The wx.EVT_ENTER_WINDOW
# wx.EVT_LEAVE_WINDOW?
#
# 2. wx.RadioBox Seems Not To Receive The wx.EVT_ENTER_WINDOW Event
#
# 3. wx.SpinCtrl (And Probably Other Controls), When Put In A Sizer, Does Not
# Return The Correct Size/Position. Probably Is Something I Am Missing.
#
# 4. Other Issues?
#
#
# FIXED Problems
#
# 1. Now BalloonTip Control Works Also For TaskBarIcon (Thanks To Everyone

:class:`BalloonTip` is a class that allows you to display tooltips in a balloon style
window.
Description
===========
:class:`BalloonTip` is a class that allows you to display tooltips in a balloon style
window (actually a frame), similarly to the windows XP balloon help. There is
also an arrow that points to the center of the control designed as a "target"
for the :class:`BalloonTip`.
What it can do:
- Set the balloon shape as a rectangle or a rounded rectangle;
- Set an icon to the top-left of the :class:`BalloonTip` frame;
- Set a title at the top of the :class:`BalloonTip` frame;
- Automatic "best" placement of :class:`BalloonTip` frame depending on the target
control/window position;
- Runtime customization of title/tip fonts and foreground colours;
- Runtime change of :class:`BalloonTip` frame shape;
- Set the balloon background colour;
- Possibility to set the delay after which the :class:`BalloonTip` is displayed;
- Possibility to set the delay after which the :class:`BalloonTip` is destroyed;
- Three different behaviors for the :class:`BalloonTip` window (regardless the delay
destruction time set):
a) Destroy by leave: the :class:`BalloonTip` is destroyed when the mouse leaves the
target control/window;
b) Destroy by click: the :class:`BalloonTip` is destroyed when you click on any area
of the target control/window;
c) Destroy by button: the :class:`BalloonTip` is destroyed when you click on the
top-right close button;
- Possibility to enable/disable globally the :class:`BalloonTip` on you application;
- Set the :class:`BalloonTip` also for the taskbar icon.
Usage
=====
Usage example::
import wx
import wx.lib.agw.balloontip as BT
class MyFrame(wx.Frame):
def __init__(self, parent):
wx.Frame.__init__(self, parent, -1, "BalloonTip Demo")
panel = wx.Panel(self)
# Let's suppose that in your application you have a wx.TextCtrl defined as:
mytextctrl = wx.TextCtrl(panel, -1, "I am a textctrl", pos=(100, 100))
# You can define your BalloonTip as follows:
tipballoon = BT.BalloonTip(topicon=None, toptitle="textctrl",
message="this is a textctrl",
shape=BT.BT_ROUNDED,
tipstyle=BT.BT_LEAVE)
# Set the BalloonTip target
tipballoon.SetTarget(mytextctrl)
# Set the BalloonTip background colour
tipballoon.SetBalloonColour(wx.WHITE)
# Set the font for the balloon title
tipballoon.SetTitleFont(wx.Font(9, wx.FONTFAMILY_SWISS, wx.FONTSTYLE_NORMAL, wx.FONTWEIGHT_BOLD, False))
# Set the colour for the balloon title
tipballoon.SetTitleColour(wx.BLACK)
# Leave the message font as default
tipballoon.SetMessageFont()
# Set the message (tip) foreground colour
tipballoon.SetMessageColour(wx.LIGHT_GREY)
# Set the start delay for the BalloonTip
tipballoon.SetStartDelay(1000)
# Set the time after which the BalloonTip is destroyed
tipballoon.SetEndDelay(3000)
# our normal wxApp-derived class, as usual
app = wx.App(0)
frame = MyFrame(None)
app.SetTopWindow(frame)
frame.Show()
app.MainLoop()
Window Styles
=============
This class supports the following window styles:
================ =========== ==================================================
Window Styles Hex Value Description
================ =========== ==================================================
``BT_ROUNDED`` 0x1 :class:`BalloonTip` will have a rounded rectangular shape.
``BT_RECTANGLE`` 0x2 :class:`BalloonTip` will have a rectangular shape.
``BT_LEAVE`` 0x3 :class:`BalloonTip` will be destroyed when the user moves the mouse outside the target window.
``BT_CLICK`` 0x4 :class:`BalloonTip` will be destroyed when the user click on :class:`BalloonTip`.
``BT_BUTTON`` 0x5 :class:`BalloonTip` will be destroyed when the user click on the close button.
================ =========== ==================================================
Events Processing
=================
`No custom events are available for this class.`
License And Version
===================
BalloonTip is distributed under the wxPython license.
