BalloonTip is a class that allows you to display tooltips in a balloon style
window.
Description
===========
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 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 BalloonTip frame;
- Set a title at the top of the BalloonTip frame;
- Automatic "best" placement of BalloonTip frame depending on the target
control/window position;
- Runtime customization of title/tip fonts and foreground colours;
- Runtime change of BalloonTip frame shape;
- Set the balloon background colour;
- Possibility to set the delay after which the BalloonTip is displayed;
- Possibility to set the delay after which the BalloonTip is destroyed;
- Three different behaviors for the BalloonTip window (regardless the delay
destruction time set):
a) Destroy by leave: the BalloonTip is destroyed when the mouse leaves the
target control/window;
b) Destroy by click: the BalloonTip is destroyed when you click on any area
of the target control/window;
c) Destroy by button: the BalloonTip is destroyed when you click on the
top-right close button;
- Possibility to enable/disable globally the BalloonTip on you application;
- Set the BalloonTip also for the taskbar icon.
Usage
=====
Usage example::
# let's suppose that in your application you have a wx.TextCtrl defined as:
mytextctrl = wx.TextCtrl(panel, -1, "i am a textctrl")
# you can define your BalloonTip as follows:
tipballoon = BalloonTip(topicon=None, toptitle="textctrl",
message="this is a textctrl",
shape=BT_ROUNDED,
tipstyle=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.SWISS, wx.NORMAL, wx.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)
Window Styles
=============
This class supports the following window styles:
================ =========== ==================================================
Window Styles Hex Value Description
================ =========== ==================================================
``BT_ROUNDED`` 0x1 `BalloonTip` will have a rounded rectangular shape.
``BT_RECTANGLE`` 0x2 `BalloonTip` will have a rectangular shape.
``BT_LEAVE`` 0x3 `BalloonTip` will be destroyed when the user moves the mouse outside the target window.
``BT_CLICK`` 0x4 `BalloonTip` will be destroyed when the user click on `BalloonTip`.
``BT_BUTTON`` 0x5 `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.
