The “brand new” Previewer

Hello KDE addicted =)

Finally i’m back to my regular life after a month spent by the sea in the south of Italy at 70km from my city, away from computers and tech in general. Unfortunately i didn’t take so much photos of me, i just found this (a night in a pub =) ):

Ok let’s get back talking about the Previewer =).

I restarted with new ideas for the Previewer applet having a look at this mockup by nuno by Nuno. So i started reviewing the Previewer keeping in mind this mockup. Here is what i got:

the new previewer

the new previewer

I feel “almost there” but there is still something to polish. Fortunately i could use some of folder view’s code to make that kind of view. But don’t get scared, the good old PreviewDialog is still there, you just have to click on the file you want to preview to get this:



Now the Dialog is cleaner without the file list (no need since the files are in the applet) and without the resize button O.O. Yes, i removed the resize button (awful way of resizing) since i added the setResizeCorners() method to Plasma::Dialog. Now the dialog resizes easily dragging its corners. Really easier and nicer than before, finally! ๐Ÿ™‚

The trash button has changed its behavior since now it closes and removes the file from the disk.

And last but not least the “run” button. It just executes the right application to open the file =).

I’m quite busy these days for my exams but i’d like to have the previewer ready for kdereview->kdebase so please test it and tell me your suggestions, ideas, critics =).


PS: finally the new planetKDE, and i’m back to blogging =).

    Great work! Personally, I still wait for some MacOS X-style QuickLook-like function (press Space bar when a file is selected, get instant preview)… But this is certainly great! Oh, and YAY for the resizing. Finally! ๐Ÿ™‚

    @Francesco: ciao Francesco,
    if you press the spacebar while a file is selected in dolphin or folderview a preview is shown with Previewer currently (if you have trunk) =)

    don’t get me wrong, but in which cases are you using this previewer? Personally, I can’t imagine to use it..

    Therefore it’s interesting to know HOW/WHEN others use it ๐Ÿ™‚
    Why should I preview a file? (probably it’s faster, anything else) And why as a plasmoid?

    Bye ๐Ÿ™‚

    @somebody: i can’t get you wrong since many of you asked the same =)

    If you don’t feel the need to use a software simply don’t use it, since software (at least this) have to ease your interaction with PCs.

    Btw I often explain through a use-case suggested to me by a friend:
    you install some software youโ€™ve never used before. It gives you Readme/Documentation and installs instructions in three different files while you need to config/setup your app on the terminal: just open the files with previewer and switch among them. Then close them when you finish =).

    Since the dialog is nice and small, you can keep it in a corner of the screen and check a file of your chose while doing your work. I find it useful when i download some files and just want to have a “quick look” at them =).

    As a plasmoid because it performs a simple task and i found it nice to made as a plasma applet. ๐Ÿ™‚

    In the future Previewer could be used to keep track of changes made to remote files hosted on an ftp server and quickly preview them to see whether changes have been made or not.

    Looking good. I have no idea if I’ll use it, but it’s great to see all these improvements going on. I do like the glassy look of the file list background, it really matches the dark Oxygen theme borders of the plasmoid. GG!

    I love this applet! Very handy. Thanks so much for the time you’ve put into it.

    Hey Alessandro!

    This looks amazing. I really like this previewer. I am doing academic work, often on several projects at a time which always involve taking notes and translating. I have the silly habit of frequently saving files under new names to keep track of changes. This plasmoid is very helpful since it allows me to quickly browse through groups of files, preview them and open those that are relevant.

    Keep up the great work!

    this is bit off-topic, but you seem like a right person to give this little feedback I have.

    I just would like to see the +/- file selection method in the plasmoid. You know, the method used in Dolphin. The plasmoid’s looks and behavior would come more consistent to the filemanager, and it is just really handy way to select few files.

    ciao ale,
    is it possible to use your plasmoid in macosX style with the kde 4.3.2?
    I don’t have trunk…
