Installation and getting started with first app

andre

/me is thinking that instead of building a tree like that himself, he would use a QFileSystemModel instead...

KennedyDayala

thanks a lot...I will try with QFileSystemModel too..

"The program can't start because mingwm10.dll is missing from your computer.Try reinstalling the program to fix this problem."

..i am getting this error when i tried running my application in stand alone mode...any help ??

giesbert

YOu are startin g without QtCreator, right?

Did you try to search the forum for answers?

see this "post":http://developer.qt.nokia.com/forums/viewthread/4869

KennedyDayala

yes Gerolf..I searched..everybody says that we need to set the invironment varioables..I did that too but of no use..

giesbert

put the needed dlls beside your exe or set the PATH environment variable to contain the path to mingw10.dll.

KennedyDayala

I have set the PATH environment variable..but it says QtCode4.dll is missing !!

giesbert

QtCode4? what's this? or do you mean QtCore4.dll?
Then the path to this dll is miossinmg :-)
You have to add it also.

KennedyDayala

sorry..that was typo..QtCore4.dll is correct..but where will this DLL reside ?

giesbert

you find it inside your Qt installation
depends which version you installed
In Qt SDK with Qt 4.7.2, look here:

<QtSDK Dir>\Desktop\Qt\4.7.2\mingw\bin

KennedyDayala

excellent Gerolf..it is working now..but my icons on buttons and Toolbar are missing in standalone application..

giesbert

How did you add them?
using from the file system or add them to a qrc file?

Could be some missing image format plugins. Please look in the forum search for "imageformats plugins", it was discussed recently with some hints about how to resolve this issue.

KennedyDayala

yep...now I understood how to create .qrc file..many thanks..

KennedyDayala

i have 7 strings with me..I would like to show them in a text editor line by line...how would i do that ??

KennedyDayala

I have used Insert() method to do that..thanks for no reply :-)

KennedyDayala

now I am showing all my available drives in my Tree widget and upon selection am able to display the total/free size of the drive. Now I want to implement two things..

1.load icons depending upon the drive type in my tree widget
2.if it is CD-ROM drive disable the user section

could somebody guide me on this !!!

Again (mentioned this before, I believe), take a look at QFileSystemModel. It does this for you already. If you don't use it yourself, then you might study its source code to find out where it gets the images from. Or, look into QFileIconProvider.

If you are using QSystemStorageInfo as your data source, then you also know which drives are a CDRom drives. Set the correct flags for those drives, and presto.
