Search all classes and source code of the Qt library at high speed with freeware.

Find class names as you type, search and copy code examples quickly, and learn by flying over Qt code with a portable freeware tool for Windows.

  • Download QView and store it in a new folder. (Right click on the link, then Save Link As.)
    QView is a freeware edition of Depeche View, a realtime text research tool.
  • Download the Qt Source Code Archive  into the same folder where QView.exe is located. Make sure to download the release 4.8.3 .tar.gz only, with a size of 233.635.127 bytes.

    After all downloads, your folder should look like:

    If you are using the Google Chrome browser, then it may have saved the text archive with a wrong file extension (redundant .tar.gz). This is no problem, it should work although.

  • Run QView by a double click.

    It will start to load all text from the file Qt Source Archive File immediately.
    Loading will take about 45 seconds on an average machine.

    The tool loads all ASCII text files from the archive. Binary files like .jpg or .png images are skipped.

  • Start searching by typing any word that comes to your mind, e.g. class.
    As soon as you stop typing, the word is searched.

    On a current computer, all occurrences of class should be found in less than 5 seconds across 20,000 files, at a speed of Mach 10 or higher.

  • All text lines containing the searched word are listed in a Filtered View.

    Just click into any of those lines to jump to that text place immediately.

  • You may also search words by clicking on them with the left mouse button, then select the search icon.

    Or by a right click on a word, to have it searched instantly in another window.
    Long words are found faster than short ones.

    QView is free for personal, non commercial use. Commercial users have to purchase Depeche View Pro, which can not only search the Qt sources, but all text files of a folder, or .tar.gz, .tar.bz2 or .zip archive file, plus many more features. More infos and a free Trial are available here.
