PyQtをUbuntuにインストールしマインドマップをHTMLやWikiに変換するツールをつくる

PyQtが面白くなってきたので、Ubuntuにもインストールする

インストール

PyQtを探す

$ apt-cache search pyqt4
python-pyudev - Python bindings for libudevpython-qt4 - Python bindings for Qt4
python-qt4-dbg - Python bindings for Qt4 (debug extensions)python-qt4-dbus - D-Bus Support for PyQt4

           :

インストール

$ sudo apt-get install python-qt4

以上。

使ってみる

普段いろいろなメモや検討、読書の要点などをまとめるのに、Androidの Mindjet というマインドマップアプリを使っている。
