Today we will be looking at how to get the selected cells from a wxPython grid object. Most of the time, getting the section is easy, but when the user selects more then one cell, getting the selection becomes more complicated. We will need to create some sample code to show how all this fits […]

The wxPython GUI toolkit comes with lots of widgets. We will be covering some widgets that are somewhat harder to get ones mind wrapped around. In this case, we will be talking about splitter windows. WxPython includes three types of splitter windows: wx.SplitterWindow fourwaysplitter which you can find in wx.lib.agw MultiSplitterWindow which you can find

Every now and then, I see someone wondering how to create a progress bar and update it. So I decided to whip up an example application that updates a progress bar (technically a wx.Gauge widget) from a thread. In this tutorial, we will create a frame with a button. When the button is pushed, it

Today I was reading the wxPython Google group / mailing list and there was someone asking about how to make Python’s logging module write its output to file and to a TextCtrl. It turns out that you need to create a custom logging handler to do it. At first, I tried just using a normal

I recently tried to help someone (on the wxPython mailing list) figure out how to use a Grid widget (wx.grid.Grid) via XRC. It should be simple, but if you run the code below, you’ll discover a weird issue: import wx from wx import xrc ######################################################################## class MyApp(wx.App): def OnInit(self): self.res = xrc.XmlResource(“grid.xrc”) frame = self.res.LoadFrame(None,

My wife teaches 3rd grade math and she recently learned about the process of obtaining the digital root of numbers. The digital root is a single digit number found by summing the individual digits. So for 15, you would add 1+5 to get 6. Thus 6 is the digital root of 15. The trainer that

This topic comes up from time to time every year. Someone will ask about how to make their application full screen or how to just make it maximize when it first loads. So we’ll spend a little time showing you how to do each of these activities.

The PySide GUI toolkit for Python has several standard dialogs and message boxes that you can use as-is. You can also create custom dialogs, but we’ll be saving that for a future article. In this post, we will cover the following dialogs: Color Dialog File Dialog Font Dialog Input Dialog Print & Print Preview Dialogs

As I learn PyQt and PySide, I am writing some tutorials to help my fellow travelers. Today we’ll be looking at how to connect multiple widgets to the same slot. In other words, we’ll be binding the widgets signals (basically events) to slots (i.e. callables like functions, methods) which are better known as “event handlers”.

This week, I needed to figure out how to attach an event handler that would fire when I double-clicked an item (i.e. row) in an ObjectListView widget that was in LC_REPORT mode. For some reason, there isn’t an obvious mouse event for that. There is an EVT_LIST_ITEM_RIGHT_CLICK and an EVT_LIST_ITEM_MIDDLE_CLICK, but nothing for LEFT clicks

Today on StackOverflow I saw someone who wanted to know how to drag a file from a wx.ListCtrl onto their Desktop or somewhere else in the file system. They were using the file manager skeleton from zetcode, but couldn’t figure out how to add the DnD portion. After a bit of searching and hacking, I

Today we’re going to take a look at Tkinter! I was curious about how one would go about hiding a frame and then re-showing it using Tkinter and I kept finding threads (like this one) that talked about using withdraw() and deiconify() but didn’t really provide any usable code. In wxPython, I did this sort
