Re: [Interest] How do Events Cascade to Child Widgets
hi, do you want to just inject or - like me - record and play events for testing and simulation purpose? For recording you can override QApplication::eventFilter and store a copy of the event together with receiver name and class name. Later on you can play all recorded events by searching for your receiver in allWidgets() and just do a sendEvent(...). This will even work for moved/resized qt widgets, for the events are directly send to the widgets. But you must have put in a name for the objects. I'm on windows so the next levels are system hooks for recording and SendEvent or alike for sending events. Though i haven't tried this yet, i except them to be received from QApplication as normal user events, thus beeing forwarded as any other event, to a receiver who feels responsible for this event, e.g. a QLineEdit with focus or a QPushButton at the mouse position. Doing it this way, you'll surely not get the still-works-with-moved-resized feature, though. alex -- /* * BOFH excuse #24: * * network packets travelling uphill (use a carrier pigeon) */ signature.asc Description: PGP signature ___ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
Re: [Interest] Qt Application deployment across platforms

No, it can't. You need to recompile per platform. Even QML applications need recompilation because you can't have a pure QML application. There's no interpreter for it, except maybe on Blackberry 10 or SailfishOS. But we should be trying to get there, IMO. The new qml tool (just qml, as opposed to qmlscene/qmlviewer) is intended for that. https://codereview.qt-project.org/#change,43540 It can be used as a shebang handler on Linux/Unix platforms, and as the default application to handle the .qml file type when you double-click a qml file in the file manager on all 3 desktop platforms. We should also make sure that it can be installed as an application on Android and iOS, and that it will show a file dialog by default so you can pick your qml file if it was not given. But AFAIK on iOS and Android it's not straightforward to put an icon on the home screen which simply points to an arbitrary file and uses the file association mechanism to launch an application to open it. Maybe we can expect this situation to be improved later, if the vendors want us to take tablets seriously as real computers. Even if all platforms supported that, it's still hard to package a whole application in a single QML file, although it can be done. Typically there are multiple QML files, images and other resources. You can get by without icon images if you use Unicode characters for all the icons though; if you can't find suitable glyphs, you can use a dingbat font, but then the user might not have the font pre-installed. QML could perhaps benefit from some kind of binary embedding method (base85 like Postscript has, base64 or uuencoding as in email attachments, or the like). But usually you would tend to need some kind of bundle. Then having an executable is only a little bit bulkier, at least until you conclude that you need to package a fixed version of Qt with it too. Then you are better off with static Qt and compiled-in resources to make a single file which is the entire application, and is as small as possible. Better yet, when we have the QML compiler finished you could use that. It's a slippery slope because of the lack of a cross-platform standard for some kind of script-bundle. That should have been solved already long ago, because there have been scripting languages for so long. But scripts have a bad rap for multiple reasons, even though some of the reasons are irrational. The question becomes, why do you always groan when you see that something which claims to be an application is written with Java or Air or VisualBasic or Python? I know that I do; and after my experience as a Java developer I know the reasons why we used t o say that groan is irrational, too. I still prefer applications to be as small and fast and have as few dependencies as possible, which is why the QML compiler will end up being quite important, IMO. But I also think there is a place for single-file QML utilities which can be launched by file association with the qml tool. A QML file can be much smaller than the executable that it generates, after all. The existence of Qt Quick Controls should make it easier than it was before.

Re: [Interest] Accessing the raw value of QQmlScriptString (QDeclarativeScriptString::script)
On Wednesday, 4 September 2013 23:18:21 CEST, Michael Brasser wrote:
The QQmlExpression constructor that takes a QQmlScriptString
allows setting a custom context and scope object to replace the
default one provided by the QQmlScriptString. Is this enough to
accomplish what you need?
Could be, I guess. I don't have enough insight into how much overhead this
would impose, though (there is no point in keeping the original context
around if it's going to be discarded anyway, etc.). I still like passing
just the actual string expression around, and delegating optimizaiton like
precompiling it, setting up a proper context etc etc until the point it is
used for validating the user-provided data.
Another reason for this is to be able to treat both modules separately --
the fact that the validation also happens to use the QML engine behind the
scene shall, IMHO, remain as an implementation detail.
This was removed in commit
aa25ad8d5f476d6db59012a122833ebe677eaf69 (Allow for future
optimization by encapsulating the raw script data.).
Unfortunately I do not remember the details of the optimizations
being discussed at the time (it may have been related to memory
consumption, or to pre-compiling QML, or to early prototypes of
v4).
Looks like I *can* get away with working with strings by extracting the
actual script value roughly like this:
QString text = QQmlExpression(scriptString).expression();
The only difference is that the expression text is now wrapped by
(function $() { return XYZ }) where XYZ is the original expression. I
could either strip this extra wrapping, or just append () to the end of
the expression.
So, shall I just stop worying about this and start passing QQmlScriptString
instances around (and if so, why)? Or shall I keep my () hack for now? To
me, the best course of action seems to be adding the script() accessor
back, but one would have to check that the returned data do not include the
wrapping, IMHO.
With kind regards,
Jan

[Interest] QAbstractEventDispatcher
Good morning, I am trying to implement my own event loop. I am trying to use libpurple which uses glib with a Qt application I am developing [1]. On Linux the application runs fine. On windows the application is unstable and will freeze. Working on the assumption that the Windows version of Qt is not using the glib eventloop I set about re-implementing the event loop using the QAbstractEventDispatcher. I am concerned for two reasons: 1, Perhaps this isn't the correct approach at all? (Perhaps the libpurple should be in a different thread altogether ???). 2, There is a lack of good examples regarding Qt and 3rd party glib implementations for which I believe the class was designed for. I was ploughing ahead with it anyway on the basis that it would be a good exercise, however I am getting lost. Such as the registerTimer function [2], where is the timerId value from?
