I can’t find the Example Demos
I can’t find the example demo in my QT installation.
But I’ve installed it, as I can see it in the Maintain QT SDK.
They are not under the Qt 4 submenu. As stated in the doc.
There is no executable for qtdemo anymore in the sdk.
But as you have choosen to install them you should find a map with the sources and a .pro file.
Your other choice is using qt Creator’s welcome screen. That way you can open the same sources and compile there.
It’s a pity they are not installed anymore because they help a lot to find the right examples.
I haven’t done it myself because i still have an old installation with the executable.
But you should be able to compile it using
- qmake -project
In the directory where you find the qtdemo.pro file.(is that the correct Filename?,i’m just posting from my mobile wihout the sources at hand)
I tried to build the example (in QT Creator, Build > Build Project “examples”) opening the examples.pro, but it gave me the following 4 warnings and errors.
C:\QtSDK\Examples\examples-build-desktop\graphicsview\portedasteroids\..\..\..\4.7\graphicsview\portedasteroids\ledmeter.cpp:-1: In member function ‘virtual void KALedMeter::paintEvent(QPaintEvent*)’:
C:\QtSDK\Examples\examples-build-desktop\graphicsview\portedasteroids\..\..\..\4.7\graphicsview\portedasteroids\ledmeter.cpp:146: warning: comparison between signed and unsigned integer expressions
:-1: error: cannot find -lpnp_basictoolsd
:-1: error: collect2: ld returned 1 exit status
and it stopped.
Why there would be any error.
Edit : Im gonna try with the demos.pro
the examples are compiling without any problem and the demo error is a known bug [bugreports.qt.nokia.com]
Edit: @jim_kaiser: How come you always post when I’m just writing mine. But you’re right, it is platform dependent (see also the bugreport I linked to). However, I still think that linking to private headers is bad practice since those are not part of the public API and can be changed or removed.
EDIT2: Correction. I was a little early to claim the examples were compiling. In fact I get the same error.
But hey… i just compiled the qtdemo.pro and it worked. Qt Creator 2.2.0 .. SDK 1.1.1
[Edit: Sorry.. I assumed we were talking about Linux.. Works in Linux. In Windows I should check.. tomorrow at work! But yeah mostly it should just be about adding an include directory maybe..]
[Edit again: Okay known bug… I shall rest..]
@loladiro: It doesn’t compile on linux for you? Works for me.. And hehe… we do tend to post simultaneously! And yeah the private files are probably not needed.. We do link to one in our application at work… but we also maintain our patch in the related classes each version.. so thats okay :P. Could you check if using “QtGui/private/qpixmapdata_p.h” works? In case the sub dirs are not added in the include path. But if not needed on Windows as the bug report says.. can be commented i presume.
