Creating a resource file to use it in Qt Designer

Question

I want to add a background image to a widget and thus I need a resource file but I am not able to create it in Qt Designer. Here is what I did:

1. From the widget I go to the resources browser and click on the "add new file" button then a new window pops up.

2. I am asked to point to the .qrc file but this file does not exist and I don't know how to create it.

I googled and found that .qrc files are created using Qt Creator.

Can't I create a .qrc file in Qt Designer ? Do I need to use Qt Creator to create a .qrc file and then use it in QT Designer ?

I am using Qt Designer with PyQt in CentOS 7.0

Answer 1

I would use Qt Creator, since Qt Designer is built in and you can simply create resource files. However, if that's not possible for you, here's a simple qrc data file contents that you can use: -

<RCC>
    <qresource prefix="/images">
    </qresource>
</RCC>

It creates a prefix called "/images/", ready to add images to the resource. Just create a file with .qrc extension and add that.

I created a file named np.qrc that has the code you provided and loaded in to resource but there is no prefix created. – Biskra

Does the file load when you open it and can you edit it from there? – Sloatman

I was making some stupid mistake. Its done thanks a ton. Can you tell me how to install QT Creator on Centos 7.0. I have tried the following: yum install qt-creator and also I tried to install it by yum install qt..BTW thanks a lot for your help. – Biskra

Download it from here: qt-project.org/downloads Click on "Show Downloads" at the bottom of the page and then scroll down to the section for Qt Creator. There's a 32 and 64-bit version, as well as the source code. – Sloatman

Answer 2

You only need Qt Designer, and it can be done very easily, like this:

1. Open the Resource Browser (View -> Resource Browser)
2. Click the Edit Resources button (first on the left)
3. Click the New Resource File button (first on the left)
4. Enter a file name (e.g. resources.qrc) and click Save
5. Click the Add Prefix button (fourth from the left) and enter a name (e.g. images)
6. Click the Add Files button (fifth from the left) and add your resources
