RulerCtrl implements a ruler window that can be placed on top, bottom, left or right to any wxPython widget.
RulerCtrl implements a ruler window that can be placed on top, bottom, left or right to any wxPython widget. It is somewhat similar to the rulers you can find in text editors software, though not so powerful.
RulerCtrl has the following characteristics:
And a lot more. See the demo for a review of the functionalities.
Usage example:
import wx
import wx.lib.agw.rulerctrl as RC
class MyFrame(wx.Frame):
def __init__(self, parent):
wx.Frame.__init__(self, parent, -1, "RulerCtrl Demo")
panel = wx.Panel(self)
text = wx.TextCtrl(panel, -1, "Hello World! wxPython rules", style=wx.TE_MULTILINE)
ruler1 = RC.RulerCtrl(panel, -1, orient=wx.HORIZONTAL, style=wx.SUNKEN_BORDER)
ruler2 = RC.RulerCtrl(panel, -1, orient=wx.VERTICAL, style=wx.SUNKEN_BORDER)
mainsizer = wx.BoxSizer(wx.HORIZONTAL)
leftsizer = wx.BoxSizer(wx.VERTICAL)
bottomleftsizer = wx.BoxSizer(wx.HORIZONTAL)
topsizer = wx.BoxSizer(wx.HORIZONTAL)
leftsizer.Add((20, 20), 0, wx.ADJUST_MINSIZE, 0)
topsizer.Add((39, 0), 0, wx.ADJUST_MINSIZE, 0)
topsizer.Add(ruler1, 1, wx.EXPAND, 0)
leftsizer.Add(topsizer, 0, wx.EXPAND, 0)
bottomleftsizer.Add((10, 0))
bottomleftsizer.Add(ruler2, 0, wx.EXPAND, 0)
bottomleftsizer.Add(text, 1, wx.EXPAND, 0)
leftsizer.Add(bottomleftsizer, 1, wx.EXPAND, 0)
mainsizer.Add(leftsizer, 3, wx.EXPAND, 0)
panel.SetSizer(mainsizer)
# our normal wxApp-derived class, as usual
app = wx.App(0)
frame = MyFrame(None)
app.SetTopWindow(frame)
frame.Show()
app.MainLoop()
