Please be aware of this when you apply them to the latest builds of Qt. QLibrary will not do this check for you. If the library is Qt based and only used within a Qt application then this is probably the best approach. The plugin approach is generally the easier one to set up and use as you can drop in more plugins into the application without too much of a problem.

Finally, in order to break up your code into several dll's, you could simply create shared libraries that you link against, see:. There are a two basic methods for calling a function from one thread on a QObject in another thread. In the mousePressEvent you can store the position for the mouse press and use that in the mouseMoveEvent in order to calculate the value for the rotation. You find dist targets in both the generated Makefile. Debug and Makefile. You can create an Eclipse Make Target with target 'dist' and build command 'make -f Makefile.

Release' to use it from Eclipse. By spreading the use of Qt as widely as possible and establishing a robust ecosystem. In order to make other members of the class available to the engine you can use one of the following approaches:.

It is the job of the layout to determine the size and position of the widgets. So if you explicitly resize a child widget which is inside a layout, you need to ensure that the new size is passed correctly through the layout system. The value returned by the sizeHint will be used when the layout calculates the new size.

This is the expected behavior. Unless you specify the font or palette explicitly yourself for a widget then the system font will override your font settings. When having a transformation set and not using anti-aliasing then if you draw something that's smaller than a pixel, you are not guaranteed that it will get drawn. In order to guarantee that it shows up you need to either turn on anti-aliasing or draw using a cosmetic pen.

It does not matter which one you use. When a given key is continuously pressed it results in a continuous stream of events for the associated key. You can not stop the events from being sent since they come directly from the windowing system. It is not possible to capture events for the delegate in a custom class. This is necessary because the delegate installs an event filter on the editor for the cell after the external event filter is installed, meaning it is always going to get the event first.

You also need to call. You probably also want to run Eclipse with a higher memory limit, so call eclipse from the command line, with e.

When creating an application on Leopardthen in order for the application to run on both Note that if you are using native calls then you will have to add checks yourself to ensure that it works correctly for all versions of the operating system. You can for example use. This problem is most likely related to you having had a previous version of Qt installed or that a Qt application that uses the named plugin is still running.

Open the task manager and close down all Qt applications and restart the build.These events can come from any number of different types of sources such as file descriptors plain files, pipes or sockets and timeouts. To allow multiple independent sets of sources to be handled in different threads, each source is associated with a GMainContext. A GMainContext can only be running in a single thread, but sources can be added to it and removed from it from other threads.

Each event source is assigned a priority.

Values less than 0 denote higher priorities. Values greater than 0 denote lower priorities. Events from high priority sources are always processed before events from lower priority sources. Idle functions can also be added, and assigned a priority. These will be run whenever no events with a higher priority are ready to be processed.

The GMainLoop data type represents a main event loop. This continuously checks for new events from each of the event sources and dispatches them. It is possible to create new instances of GMainLoop recursively. Note that event sources are associated with a particular GMainContextand will be checked and dispatched for all main loops associated with that GMainContext. One of the unusual features of the GMainLoop functionality is that new types of event source can be created and used in addition to the builtin type of event source.

A new event source type is used for handling GDK events. A new source type is created by "deriving" from the GSource structure. The derived type of source is represented by a structure that has the GSource structure as a first element, and other elements specific to the new source type. These GSourceFuncs determine the behavior of the new source type. New source types basically interact with the main context in two ways. Their prepare function in GSourceFuncs can set a timeout to determine the maximum amount of time that the main loop will sleep before checking the source again.

In some cases, more detailed control of exactly how the details of the main loop work is desired, for instance, when integrating the GMainLoop with an external main loop. The operation of these functions can best be seen in terms of a state diagram, as shown in this image. Any program using the mainloop must either exec or exit from the child without returning to the mainloop.

There are two options for memory management of the user data passed to a GSource to be passed to its callback on invocation. In many cases, it is an error for the callback to be invoked after this owning object has been destroyed, as that results in use of freed memory.

This ensures that the callback can only be invoked while the object is still alive. This ensures that the object is kept alive until after the source is finalized, which is guaranteed to be after it is invoked for the final time. It is called when the source is finalized, and is designed for releasing references like this. One important caveat of this second approach is that it will keep the object alive indefinitely if the main loop is stopped before the GSource is invoked, which may be undesirable.

Creates a new GMainLoop structure. Increases the reference count on a GMainLoop object by one. Decreases the reference count on a GMainLoop object by one. If the result is zero, free the loop and free all associated memory. If this is called for the thread of the loop's GMainContextit will process events from the loop, otherwise it will simply wait.

Stops a GMainLoop from running. TRUE if the mainloop is currently being run.Offering a complete set of UI elements, GTK is suitable for projects ranging from small one-off tools to complete application suites. Developers around the world have used GTK as a platform to create apps that solve problems faced by end-users. Check out this easy tutorial on how to create a toolbar using Glade.

GTK has all the features that a widget toolkit needs to have. These features make it the most trusted toolkit for developing Linux applications. GTK has a comprehensive collection of core widgets like Buttons, Windows, Toolbars for use in your application. GTK boasts of an easy to use API which helps in decreasing your development time and help you achieve better results.

GTK is built on top of GLib. GLib provides the fundamental data types and system integration points to avoid duplicated code in applications. If you are interested in developing an app, get started now by developing this example application. GTK is a large project and relies on volunteers from around the world. To help us with the project development, hack away on the existing bugs and feature requests. You can use tags like gtk or glib to narrow down the topic of discussion to specific libraries.

You can also ask questions on our IRC channel. As regularly as possible, GTK team meetings take place at conferences and hackfests to discuss the future of GTK and define a roadmap. If you are a developer and want to contribute to GTK, you are more than welcome to do so.

The Xbox guitar and some Xbox1 dancemats might work too. The Xbox racing wheel is not supported, but shouldn't be to hard to add if somebody is interested. The cable is for recharging only and does not transmit any input data over the wire. To use the wireless Xbox controller you need the wireless receiver. In addition to all the Xbox related stuff, the driver also has native support for the Thrustmaster Dual Power 3 gamepad, including rumble and can be used on top of the regular Linux joystick driver.

Unlike the stock xpad kernel driver, xboxdrv provides a wide varity of configuration options, it allows you to simulate keyboard and mouse events, remap buttons and axes, apply autofire, invert axis, tweak axis sensitivity, emulate throttle and rudder controls and send macros. You can find a full list of possible options in the xboxdrv manpage. This releases contains a large scale switch to asynchronous USB communication, so expect some bugs to pop up.

For the time being it is recommended to stick with the 0. The development version of git aka the 0. Testers are welcome to give it a try. Chatpad support is currently working only for the wired USB controllers, not the wireless ones. As both work a little different one can't just apply code from one to the other.

Capturing the USB communication between an real Xbox and the wireless receiver should however be possible if somebody has both an USB protocol analyzer and an Xbox to take apport.

Technical FAQ

Designed for programmers with large heterogeneous trees of source code, ack is written purely in portable Perl 5 and takes advantage of the power of Perl's regular expressions. This is how you make it do stuff. See the man page for details. The main philosophy is to provide high-level track reconstruction modules that can be used for any tracking detector. The description of the tracking detector's geometry is optimized for efficient navigation and quick extrapolation of tracks.

Converters for several common geometry description languages exist. Having a highly performant, yet largely customizable implementation of track reconstruction algorithms was a primary objective for the design of this toolset. Additionally, the applicability to real-life HEP experiments plays major role in the development process.

Apart from algorithmic code, this project also provides an event data model for the description of track parameters and measurements. Key features of this project include: tracking geometry description which can be constructed from TGeo, DD4Hep, or GDML input, simple and efficient event data model, performant and highly flexible algorithms for track propagation and fitting, basic seed finding algorithms.

Details of the methods and algorithm can be found in this paper. It reads from standard input and writes to standard output. Fast searching files for a string or regular expression, with approximate matching capabilities and user- definable records.
