Posted in Qt

As some of you might have noticed we’re expanding into Germany, more specifically Berlin, even more specifically Adlershof, even EVEN more specifically Albert-Einstein strasse 16. The honorable task of getting the keys and opening the office for the very first time fell on Thomas and me, I wonder why Matthias didn’t do it himself – […]

Mouse event propagation

Posted in Qt, Qtopia

Have you ever implemented mouse handling in a Qt widget? Either in a custom widget, (that inherits QWidget directly,) or by extending some existing widget, let’s say QLabel, with interaction abilities? For the most simple cases, mouse handling is quite intuitive in Qt: just reimplement a mouse handler function (virtual function, inherited from QWidget), and […]

it’s spelled ‘Qtopia’

Posted in Qt, Qtopia

ok, have to rant here. I have worked with Qtopia and friends for several years now, and occasionally see ‘Qtopia’ spelled as “QTopia’. and for some reason, it bothers me seeing this (perhaps pedanticness?). Please, if you write about ‘Qtopia’, spell it as Q-t-o-p-i-a, there is no capital ‘T’. and if you have written it […]

There’s a new build tool around these days – cmake. Kde4 supposedly uses it, replacing the autotools configuration stuff. Now I can understand why someone would want to not use autotools – too complicated for many engineers to understand properly, and IMHO a pain in the a**. Trolltech has a great tool already – qmake.

Fast transformed pixmap/image drawing

Published Saturday May 13th, 2006 | 1 Comment on Fast transformed pixmap/image drawing
Posted in KDE, Qt, Qtopia

From time to time I hear about one particular annoyance people have with Qt’s painting architecture – that drawing transformed pixmaps is horribly slow. Scaled pixmap drawing, for example; something like this: We all know the use case: some image editor that needs to zoom in on an image to plot pixels, or perhaps someone […]

Fun with QTextEdit

Posted in Qt

One of the features that I like in a programming editor is the ability to have multiple views of the same file. It’s a little known fact that this is very easy to accomplish with QTextEdit. Try out this snippet of code: #include <QtGui> int main(int argc, char **argv) { QApplication app(argc, argv); QTextDocument sharedDocument; […]
