Yeah, OK. I'll give it a new go with the porting guide in place.
Wasn't aware of that and I had a bad day (car broke down, refrigerator stopped working, things like that) so I was quite annoyed generally.
The books probably has a slightly higher value than estimated earlier... ;-)
Book is right , but you skipped following instructions..
"All the widgets look fine now, except the text label, which shows &Cell Location. Click Edit|Edit Buddies to enter a special mode that allows you to set buddies. Next, click the label and drag the red arrow line to the line editor, then release. The label should now appear as Cell Location, as shown in Figure , and have the line editor as its buddy. Click Edit|Edit Widgets to leave buddy mode."
Be patient with Digia, they might take time to answer. Depending on where you live you could try to ask on a more local sub-forum to see if anybody could burn and send you a DVD containing the needed packages.
The MVC pattern aims
the data (model)
the visualization (view)
Provides clear responsibilities for all classes involved
Observer Pattern - When writing event-driven programs, GUI views need to respond to changes in the state of data model objects, so that they can display the most recent information possible.
When a particular subject object changes state, it needs an indirect way to alert (and perhaps send additional information to) all the other objects that are listening to state-change events, known as observers. A design pattern that enables such a message-passing mechanism is called the Observer pattern, sometimes also known as the Publish-Subscribe pattern.
There are many different implementations of this pattern. Some common characteristics that tie them together are
They all enable concrete subject classes to be decoupled from concrete observer classes.
They all support broadcast-style (one to many) communication.
The mechanism used to send information from subjects to observers is completely specified in the subject's base class.
Qt's approach is very different from Java's approach, because signals and slots rely on generated code, while Java just renames observer to listener.
[quote author="utcenter" date="1368978796"]I was considering to start a video tutorial series on Qt5, but never quite manage to find the time. The good news is that as of more recent Qt5 snapshots, the documentation begins to take shape, so people are not completely in the dark.[/quote]
Please do make them.Video tutes are the best learning tools in programming I have found so far.And when you do decide to make them,consider live coding,and..... giving me the link;-). Sometimes 10 mins of good video are better than 50 good pages.
Please checkout the ForumHelp for advice on postings. "Code wrappings":http://qt-project.org/wiki/ForumHelp#e3f82045ad0f480d3fb9e0ac2d58fb01 do improve the layout of your posting significantly. I have added them for you this time.
I would recommend that you get some good book about c++. This is a basic c++ question that's not related to Qt
// somewhere in your code
bool result = cricket::mycricketfunction(inputvariable);
bq. I just have to send the translations to firstname.lastname@example.org ?
This material now belongs to Digia, no longer Nokia, so that email-adress is a bit outdated. For now please just list the translation as in the works here: "http://qt-project.org/wiki/Learning_Material_Translations":http://qt-project.org/wiki/Learning_Material_Translations. Then when your are done, we can find out where best to host it.
[quote author="martonmiklos" date="1363686943"]I have never tried to compile it with Qt5.
I am installing the Qt5 now and
The benchmark example depends on the Qwt. I will create a simple separate example today without any extra dependencies. [/quote]
alright, i will be awaiting for the new revision. Thanks man! ^^
I'm having the same problem. Ironically, the link on some of the video pages you're supposed to click if you're having issues has issues, i.e. it is also a nokia link and just redirects to qt.digia.com. I'm new to Qt, and I like learning through lectures, so I hope that this is resolved soon.
On the video pages, a lot of people suggested using torrents as an alternative to distribute the videos. I don't know if anyone who has a say in that sort of thing will read this thread, but I would definitely second that.

Seems pretty much the same as in my country of origin.
Hello,utcenter. I am reading the Qt3D Troubleshooting. In the last part, it suggests that I should delete the values in Windows registry
@HKEY_CURRENT_USER\Software\Trolltech\OrganizationDefaults\Qt Plugin Cache 4.2.debug
HKEY_CURRENT_USER\Software\Trolltech\OrganizationDefaults\Qt Plugin Cache 4.2.false@
But in my computer,the values read this:
@Qt Plugin Cache 4.5.false
Qt Plugin Cache 4.6.false
Qt Plugin Cache 4.7.debug
Qt Plugin Cache 4.7.false
Qt Plugin Cache 4.8.debug
Qt Plugin Cache 4.8.false
Should I delete them all?
here they are:
"Your text to link here...":https://sourceforge.net/projects/qtexamples/files/
sourceforge is unnecessarily complex...grandiose
all 3 examples work but require a gunzip, tar xvf and execution (readme.txt file in each project )
sourceforge gurus advise..please
The Lottery example will be changed to allow personal selection of 6 external values
to run against 6 generated values
