Writing a bar graph widget in Qt

published at 26.04.2014 23:20

Today I had a little fun with Qt and wrote a widget for displaying a bar graph. I have two different situations where I need the bar graph in my back end: displaying the votes a single talk got, and displaying one big bar graph of all the talks.

Writing a small voting tool in Qt

published at 17.04.2014 20:41

I've just written this afternoon a small tool for the talk-vote for Meeting C++ 2014. As the call for papers ends on Sunday, the voting comes closer. Last year only a few people on the program committee could vote, this year its going to be around 300. This is 10 times more then last year. In this way I want to give the audience a chance to influence the program. I'll get into the voting details in the last paragraph.

So, for one year I've been reading Proposals for the C++ Committee, some thoughts on where its going, and where its currently at. And now that C++14 is in its final draft state, also a look into the Standards beyond C++14.

Looking at C++14

published at 14.03.2014 16:12

A few weeks ago the C++ committee meeting in Issaquah (WA;USA) ended, its most important result: the final draft for C++14, which has been published last week. As I have read through most papers of last and this year, a short overview which papers now have made it into the standard.

Analyzing websites with QtWebkit

published at 21.02.2014 19:11

I just finished a little tool, which needs to analyze websites, in this case mostly blog posts to extract a few fields. I have been working with QtWebkit for this purpose for a while, one larger project I am working on needs it to index certain websites. So, writing this small tool is a good example on how to that with Qt.

shared_ptr addiction

published at 14.02.2014 16:26

I've written earlier this year about smart pointers in C++, today I just would like to write a little more about shared_ptr. Especially about addiction to shared_ptr, and why you should use unique_ptr in C++11.

As the year is just a couple of weeks old, what can we expect from C++ in 2014?

An overview on smart pointers

published at 10.01.2014 12:20

My last blog post in 2013 was about the pointer in C++, and how most of its daily usages in C++ is now being replaced by classes replacing or managing the pointer. The last case, the RAII like objects called smart pointers is the topic of this post. I want to give an overview over the choices one can make when using smart pointers.

A look at Qt5.2

published at 12.12.2013 17:17

Suddenly a wild Qt5.2 appears. Digia and all the contributors to Qt have done once again a great job. With Qt5.2 Android and iOS are now supported, QML runs without V8 JavaScript engine on its own engine. So, some great changes come to Qt with 5.2.

Say hello to wxWidgets 3.0

published at 04.12.2013 14:40

I remember the times, when wxWidgets 3.0 was already talked about, several years ago. Now, its been published in November, though I have to take a look at it. I've been using wxWidgets for years, but moved on to Qt for my own projects. So, lets have a look at wxWidgets 3.0...

Creating zip-archives in C++

published at 22.11.2013 17:46

Today I had to do some research into how to create archives in C++, as this is my windows machine, a windows or better platformindependent solution is needed. My plan is to write a small backup tool, which simply copies folders and files (maybe with filtersupport) into an archive. Of course there is the zlib as a solution, but I'm looking for an easy way to do things, and not an C interface. So, I started my search for a solution...

Founding local C++ User Groups

published at 15.11.2013 16:39

I've talked to some people at Meeting C++ 2013 about this, but decided not to go into the details about this at this years conference. That would have meant to have another good talk not at the conference. So, here is my thoughts and a little overview on C++ User Groups. Note that a lot of what I write also applies to you, if you just want to found a User Group for something else then C++. But I use C++ User Groups as an example, as its only logically with my expierence.
