Plasma and QGesture*

Wednesday, February 24th, 2010

Plasma has support for mulitouch events but for some reasons I can’t get any QGestureEvent, does anyone have any idea about why QGesture doesn’t work with Plasma?

It seems that QGestureRecognizers can receive QEvent::TouchBegin but they can’t receive QEvent::TouchUpdate or QEvent::TouchEnd.

Any idea?

Plasma Web Browser and WebKit

Sunday, February 21st, 2010

Recently I’ve been working on the web browser plasmoid and since yesterday it’s possible to use it like a complete stand alone browser (with advanced rendering capabilities thanks to QtWebKit), moreover Plasma::WebView has been recently ported to KGraphicsWebView so it has KDE integration too.

The summary of recent changes is:

  • Plasma::WebView does the same (and better) with less lines of code.
  • Plasma::WebView uses now a KDE integrated WebKit.
  • Web Browser now supports windows (with overlays).
  • The progress bar has been replaced with a ProgressComboBox (like rekonq).

By the end of the tokamak plasma will provided to users a complete web experience.

Moving things to the right place

Saturday, August 29th, 2009

Yesterday I’ve moved desktop theme configuration from Desktop Settings to System Settings style module. Now Desktop Settings dialog looks less cluttered.

New system settings/style desktop theme configuration tab

New system settings/style desktop theme configuration tab

Now I’m still working on Desktop Settings dialog and I will continue to improve it.

Next step is to add categories to wallpaper settings.

tokamak 3 (day 0) :)

It has been a long time since my last update…

I’ve been away for a long time due to several reasons (including school exams) but now I’m here in Swiss.

Now I’m in an amazing place with stunning views and fresh. I will post more things about this tokamak later.

Don’t confuse users: Don’t say “applet”.

Tuesday, February 3rd, 2009

Use the word “applet” only in development contexts (when you are talking about Plasma::Applet), in any other case use the word “widget”.

10 rules for a plasma widgets developer

Friday, January 30th, 2009
  1. Don’t call updateGeometry() during a size constraintsEvent and don’t call resize.
    If you want to keep the same aspect ratio you may be interested in Applet::setAspectRatioMode( ).
  2. If you want to write a new clock widget, you should inherit from libplasmaclock ClockApplet.
  3. Don’t do custom things: use default plasma methods and widgets when possible.
    Some useful methods are: Applet::setBusy( ) if your applet is busy, Applet::setConfigurationRequired( ) if user needs to configure the widget, etc…
    Some useful widgets are: Plasma::CheckBox, Plasma::ComboBox, Plasma::LineEdit, Plasma::PushButton, Plasma::RadioButton, etc…
  4. Don’t reimplement Applet::showConfigurationInterface, reimplement Applet::createConfigurationInterface instead.

    void MyApplet:createConfigurationInterface(KConfigDialog *parent)
    {
    QWidget *widget = new QWidget();
    ui.setupUi(widget); //ui is your configuration interface
    parent->addPage(widget, i18n("General"), icon());
    connect(parent, SIGNAL(applyClicked()), this, SLOT(configAccepted()));
    connect(parent, SIGNAL(okClicked()), this, SLOT(configAccepted()));
    }
  5. Use Plasma::Animator and fast animations (not slower than 150 milliseconds).
  6. Use a standard background when possible.
  7. Avoid installing custom svg graphics when possible.
  8. Load graphics using Plasma::Svg.
  9. Don’t forget that the theme may change while your widget is running.
  10. paintInterface() might be called before init().

New calendar widget moved to kdereview

Plasma::Calendar Widget

Calendar Plasmoid

Finally today I moved the new calendar widget to kdereview.
This new widget is based on a nuno‘s mockup and it will be usable by any plasma application that needs a calendar (it will be part of libplasma).
One of my aims is to write something that is highly customizable so it will be possible to do cool things like integration with akonadi.
I’m planning to continue to work on it and to add some new features like ToolTip support so if you have any ideas, please email me ;)

new kickoff mockup

Monday, August 4th, 2008

Friday night I was playing with inkscape and I tried to do a kickoff mockup because I don’t like kickoff’s current look (kickoff is a white and flat rectangle that doesn’t fit really well in a black plasma theme). So, I worked all night and at 05:30 AM I finished this mockup:


(don’t forget that I’m not an artist ;) )

My idea essentially is to use user’s current plasma theme, so If the user uses the default theme he will have a black kickoff otherwise if the user uses fluffy bunny theme, user will have a fluffy bunny themed kickoff. :D

Today I started to work on it: I created a new branch called ckickoff, I removed some lines of code and I switched from Plasma::Applet to Plasma::PopupApplet.
PopupApplet allows (with a few lines of code) for showing an icon when the plasmoid is on the panel, and showing the whole plasmoid when it’s on the desktop, so now if you place kickoff plasmoid on the desktop you see kickoff launcher and not a K icon.

For now I have nothing more to say except that I’m going to Akademy:
