python - FigureCanvasWxAgg not resizing properly in panel (or notebook) in linux -


i've written program in wxpython works fine in windows when tested in lunix have display issues that occur in linux.

here testapp demonstrates problem resizing of figurecanvaswxagg in panel, seen panel self follows resizingevent figurecanvaswxagg doesn't follow, not problem in windows.

import wx import matplotlib.figure plt matplotlib.backends.backend_wxagg import figurecanvaswxagg figurecanvas import wx.lib.inspection  class test(wx.frame):      def __init__(self):         super(test, self).__init__(parent=none, id=-1)         self.figure = plt.figure()         self.panel = wx.panel(self, 1)         self.figurepanel = figurecanvas(self.panel, -1, self.figure)         self.axes1 = self.figure.add_subplot(111)         frame_box = wx.boxsizer(wx.vertical)         frame_box.addstretchspacer(prop=1)         frame_box.add(self.panel, flag=wx.expand, proportion=2)         frame_box.addstretchspacer(prop=1)         main_box = wx.boxsizer(wx.horizontal)         main_box.addstretchspacer(prop=1)         main_box.add(frame_box, flag=wx.expand, proportion=1)         main_box.addstretchspacer(prop=1)         self.setsizer(main_box)         self.show()         self.layout()  def main():     app = wx.app()     test()     wx.lib.inspection.inspectiontool().show()     app.mainloop()  if __name__ == '__main__':     main()

what grateful have answered is:

  • how resolve issue of reszing figurecanvaswxagg in linux
  • is there difference in general way of gui programming wxpython on windows , in linux

there several issues code posted:

  1. you have horizontal , vertical spacer expand needed, causes central region remain same shape
  2. self.figurepanel not part of sizer, means not resize if container, self.panel does.

the code below produces window filled plot resizes window:

import wx import matplotlib.figure plt matplotlib.backends.backend_wxagg import figurecanvaswxagg figurecanvas import wx.lib.inspection  class test(wx.frame):      def __init__(self):         super(test, self).__init__(parent=none, id=-1)         self.panel = wx.panel(self, 1)         self.panel.setbackgroundcolour('red')          self.figure = plt.figure()         self.axes1 = self.figure.add_subplot(111)         self.figurepanel = figurecanvas(self.panel, -1, self.figure)          main_box = wx.boxsizer(wx.horizontal)         main_box.add(self.figurepanel, flag=wx.expand, proportion=1)         self.panel.setsizer(main_box)          frame_box = wx.boxsizer(wx.vertical)         frame_box.add(self.panel, flag=wx.expand, proportion=1)          self.setsizer(frame_box)         self.show()         self.layout()  def main():     app = wx.app()     test()     wx.lib.inspection.inspectiontool().show()     app.mainloop()  if __name__ == '__main__':     main()

there no need manual resizing yourself, , there no problem, think, resize event propagation. if there there lot more breakage seeing.

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
