Mapping signals and slots

« 19 January 2009 | 21:58 | Programming, Qt, Qxt | No Comments »

Have you ever hoped there was a class that was able to do the opposite of QSignalMapper? For example, “If the signal parameter is 2, call that slot of this receiver. If the signal parameter is “foo”, call this slot of that receiver.” We have it now in Qxt, it’s called QxtSlotMapper. An example follows: […]



What’s my idle status?

« 25 August 2008 | 22:14 | Programming, Qt, Qxt | No Comments »

There has been a raising demand for querying the system idle time. The Qxt team runs to help again! A new method, namely QxtWindowSystem::idleTime(), was introduced last week. The current implementation covers X11 and Windows platforms. And in case you’re curious about the implementation, we did it with help of XScreenSaver and GetLastInputInfo(), respectively. A […]

A header view with proportional section sizes

« 4 July 2008 | 11:28 | Programming, Qt, Qxt | No Comments »

Here comes more Qxt news. Yesterday I introduced a header view with proportional section sizes. This makes it possible to say that for example “section A is twice as wide as section B and section C is 3 times as wide as section B”: |–A—|-B-|—-C—-| Btw, this TODO task was only 4 months old. 🙂



Say hello to QxtTabBar::TabMovementMode

« 3 July 2008 | 11:10 | Programming, Qt, Qxt | 1 Comment »

It was about the time to give Qxt some attention. Yesterday I finally took care of a TODO task added by myself in 14th of February: “draggable tabs”. Say hello to QxtTabBar::TabMovementMode: QxtTabBar::NoMovement QxtTabBar::InPlaceMovement QxtTabBar::DragDropMovement Like the name suggests, QxtTabBar::NoMovement doesn’t allow tab movement. QxtTabBar::InPlaceMovement handles moving of tabs “in place”, which means that the […]



How to switch Qt version in Ubuntu

« 16 March 2008 | 2:10 | Howtos, Linux, Programming, Qt | 13 Comments »

It’s surprising how often people seem to ponder how to switch between different Qt/Qtopia versions when they have multiple versions of Qt/Qtopia installed. All what really matters is to have the right qmake in PATH at time. Even if it might not be that hard to write a shell script to do the switch, I […]

LibQxt 0.3.0

« 5 January 2008 | 14:49 | Programming, Qt, Qxt | 1 Comment »

A few days ago, LibQxt 0.3.0 was released. Congratulations again, keep up the good work guys! I’m particularly impressed how QxtGlobalShortcut found its shape. This change derives from last fall when QxtNativeEventFilter was introduced. This gave us the possibility to refactor global shortcut aka. hotkey functionality out of QxtApplication. Today, as in LibQxt 0.3.0, QxtGlobalShortcut […]
