description Description

ZoomBar is a class that appoximatively mimics the behaviour of the Mac Dock, inside a wx.Panel.

Once you hover mouse over the ZoomBar correct button will bubble up, grow to predefined size, so you can easily see the button you are about to click and have larger area to click. Difference this makes is amazing.

The buttons are able to be zoomed from the bottom up (bottom fixed) as well as to zoom from a central point. Also the container is able to move the remaining buttons around the zoomed button.

usage Usage

Usage example:

import os
import random
import glob

import wx
import wx.lib.agw.zoombar as ZB

class MyFrame(wx.Frame):

    def __init__(self, parent):

        wx.Frame.__init__(self, parent, -1, "ZoomBar Demo")

        panel = wx.Panel(self)

        bar = ZB.ZoomBar(panel, -1)

        standard = glob.glob(bitmapDir + "/*96.png")
        reflections = glob.glob(bitmapDir + "/*96Flip40.png")

        separatorImage = bitmapDir + "/separator.gif"
        separatorReflection = bitmapDir + "/separatorFlip.png"
        count = 0

        for std, ref in zip(standard, reflections):
            if random.randint(0, 1) == 1 and count > 0:
                sep1 = wx.Bitmap(separatorImage, wx.BITMAP_TYPE_GIF)
                sep2 = wx.Bitmap(separatorReflection, wx.BITMAP_TYPE_PNG)
                bar.AddSeparator(sep1, sep2)

            bname = os.path.split(std)[1][0:-6]
            bar.AddButton(wx.Bitmap(std, wx.BITMAP_TYPE_PNG), wx.Bitmap(ref, wx.BITMAP_TYPE_PNG), bname)
            count += 1


        sizer = wx.BoxSizer(wx.HORIZONTAL)
        sizer.Add(bar, 0, wx.ALIGN_CENTER_HORIZONTAL|wx.ALIGN_CENTER_VERTICAL|wx.ALL, 15)

# our normal wxApp-derived class, as usual

app = wx.PySimpleApp()

frame = MyFrame(None)

Some of the AGW snippets of code in the documentation use images and external files (to create bitmaps or access external data). As these files are not provided in these snippets, you should make the approriate modifications to the code to actually run it.
