Creating interactive QT hello world GUI application using QT Creator.

[aloknookraj]

@jadchaar713 cpp with extensions

[jadchaar713]

Great video, its a lot like Visual Studios, just different syntax and such.

Is Qt its own language?

[KAHNonymousjohn]

Great video, I'd love it if you'd make some more.

[KAHNonymousjohn]

Great video, thanks.

[oONecauOo]

thanks for this video :_D . Now i know how to work , i was very lost with this program :S

[InHiphopWeTrust]

what's a slutbutton?

[VurigDraakje]

Thank you sir! :D I got this working on the Mobile Qt with Qt 4.7.4!! Going to make my own speedometer with bluetooth and gps.. (or atleast trying too!)

[Rukiri89]

This works but not with QT4, to get this to work create your buttonclickhandler() than drag the action to the label than the code works.

This works with the older version, not the new.

[bluetonic22]

Thx for you the effort!!

[ziodice]

Public slots doesn't work. When I type it in the header file, there is red uunder it :(

[rocidew]

Thanks!

[Ilikemustard]

Dude your accent is fucking amazing.

[zacknow]

which version of qt are you using?  I have qt creator and qt developer. in developer i cant edit the code. in qt creator i dont have the option like you on yours for adding the buttons like you do. do i need to install extra files or something.

[CalmOne13]

nice tutorial....but how to add hello world txt to another string...like i write hello world, klick button and it would say hello world, damn good one

[derabu]

Thank you!!

[ruhanbidart]

Thank you, very simple to understand!

[CamiloSanchez1979]

c++ is such a qt.

[MarwaShams]

thanks very much :)

[xistoxs]

thanks for the help :D

[bojanglesme]

i like to migrate from .Net to QT, but Qt has no video tutorials like Appdev, VTC and total training

[kayfolovka]

It works now, but I still I can not switch from Edit mode back to Design mode.  The QT creator design button is disabled.

[kayfolovka]

Thank you, for the video.

I tried to reproduce the application, but it do not work for some reason. The edit control text do not shown in the label widget. Also after first build and debug I can not switch from Edit mode to Design mode. The QT creator design button is disabled. Any suggestion?

[DRDAHOS]

thank you

[Krisler12]

I like it !

We need more Qt vid tuts if no bother !

(say all after me)

More Qt ! More Qt ! More Qt !

[dirtslayer123]

this is exactly what i needed, i was having a hard time finding how to create event handlers (slots), i did not realize you could just use the main window as a event receiver -- good job

[ison011]

thanks ^^

[vaticanantichrist]

i am taking a GUI class in the spring. I think it covers windows api though.. Topics covered include a review of the standard user interface elements of Windows, the Windows Application Program Interface (API), message processing, writing Windows Procedures, working with text, using Windows resources, creating modal and modeless dialog boxes, and using the Graphics Device Interface.

[SchindlerShadow]

OMG THANK YOU!!! no one else shows it like that!, all i wanted to know was how to use the code to change the stuff in the ui, now that i c it, its rely ez: ui->label->setText()

[FelipeSaoleopoldo]

Thanks!!! Very Thanks!!

[TheQuakeIV]

Thank you, this was very helpful.

[rubenimc]

Hey, Nice video. How is this different from VB? My important question is how do I develop an app for my Symbian phone. I have installed the QT2.0 and I hove found no way to implement an application for my mobile phone. Can you please post a video that will create a calculator/Helloworld application and give the executable file in sis,Jar/Jad formats?

[actualizator]

He does not explain anything.

What all these actions do???

Bad tutorial.

[Amaradon]

@actualizator u shouldn't try to learn it when u don't used c++ before.. If u used it before you should know what these things are about... All these people here thank him for telling them how to do it not what these actions are ;D so just learn a bit of c++ and return here ;)

[ecv80]

Helped me a lot. Thanks

[ArturoVergaraM]

I need help for compiling, do you have a tutorial on this? or could anyone PM me with instructions plz? I have already finished my program but I can't compile it :S

[Deltanova93]

Nice Tutorial;)

[edgarguevaracodina]

Your video has been a great help to me. Thanks a lot!

[leitenlexid84]

საღოლ!

[TheZEGMAN]

I cannot open the designer because after I create the GUI project it just puts me to a grey screen with no projects screen! I can't understand how to navigate the program.

[jadooindia]

good vid

[xmaop]

Thank you, thats what I looking for

[emphero100]

This is exactly what I was looking for...

[nickrohn93]

Sorry i am on linux

[nickrohn93]

On the left how did you get the source code window to show up?

[xSirFarisx]

Thanks man

[myztic123]

if i add a qt designer form (.ui) file, how do i get the .h and .cpp file for that automatically?

[vano512]

Currently as I know iPod touch is not supported.

[maw88ify]

@vano512 I like using Flash to make apps betterm and IPhone SDK will be included in the new Flash CS5 coming out soon...

[anticipayo]

@aTSa66 ,

Nope!

[jabwd]

@aTSa66 disallowed. read the liscense agreements first.

[Greenadee]

@aTSa66 No, mainly because QT is C++ and iPod Touch / iPhone uses Objective C.

[aTSa66]

@Greenadee

ok, thanks all for the answers. I understand it now ;)

[genomega]

Excellent, thank you...

[Novecento]

Thanks a lot vano! You saved me a lot of time of trials and errors! Great job!

[BalenJA]

Hello vano512, I just downloaded Qt and my very first exercise was this clearly explained video of yours. Thank you very much!

[BandytaCzasu]

Will this work under linux too?

[vano512]

Sure, QT is multi platform framework, as QT Creator the IDE itself.

[BandytaCzasu]

Im asking, cause i installed it under linux, and i can't compile anything, i get

"/usr/bin/ld: cannot find -lSM

collect2: ld returned 1 exit status

make: *** [InteractiveHelloWorld] Error 1

Exited with code 2.

Error while building project InteractiveHelloWorld

When executing build step 'Make' "

Someone knows what is wrong?

[lolzbrot]

Thx a lot! I'm looking forwards for more tutorials! :)

[Mesiaste]

thanks man!

[ahmed1on1]

thanks a bunch I made my Qt HelloWorld App too :)

[flipponzin24]

Thanks for the tutorial, sir! Well done =:-)

[altu892]

just like netbeans...

[YourAppleTechHelp]

You can´t create a GUI with netbeans... or?

[airthang]

Hi, I tried Ctrl + Space, it did Code Completion but when I type the function and press Ctrl + Space it didn't do anything. What should I do?

Thank for your video ^_^

[kadence0]

Thanks, very helpful :) I had a surprisingly hard time finding a tutorial like this.

[darkmoo1]

How did you get the code to Auto finish?

(when you where typing public slots: it pupped up with slots :?

[vano512]

what do you mean under Auto finish?

Yes it pupped up SLOT and slots. This IDE QT Creator is designed it to help you develop with QT and assist you in qt specific stuff.

[CallToPower]

Press ctrl-space to get possible auto-completion

[0121ryanh117]

In QtCreator, that happens at certain times, like when typing a method that is already defined in your header file.

[20033017]

@darkmoo1

Yes, qt is having that kind of auto finish. Technically it is called 'intellisense'.

For tht you have to press ctrl+spacebar(like visual studio).

[Sergey2189]

thanks!

[linuxieu]

Thank you very much for this video i hope you will make an other to help us

[nbdi]

Thank you very much, such tutorials are usually hard to google but they are very useful in some cases)

[prudkyjoe]

[willtco]

Thanks, a great 'Get Started' video, 100% !!

[sridatta102]

[JacobsMichiel]

[vano512]
