Are there other Qt/QML learning resources?
The consulting company ICS has a series of videos that could be helpful. Registration is required.
Where are your QML Components documented?
Due to the variety of platforms that QML runs on, by default, there are very few QML components available. Reach has provided a number of components to make development easier. Find them at QML Components.
Do I have to purchase a Qt license?
You may need to purchase a license. Please contact support at The Qt Company for your specific answer. Learn more qt.io/licensing.
Do I have to use QML/Qt, or can I use C++?
We provide a Linux Virtual Machine (VM) and a cross compiler for use in coding C and C++ applications. Learn more by visiting the Linux Quick Start Guide.
I’m constantly removing and replacing the SD Card. Is there an easier way?
Yes, there is. We recommend getting a microSD extension.
How can I improve the performance (speed) of my QML Application?
Check out this Qt Developer Days video and download the Analyzing Performance of Qt Quick Applications document.
How do I port a G2C1 application to the G2H2 module?
To port a G2C1 application to the G2H2 platform, you will need to change the QML files to account for the new QtQuick used in the new Qt Creator. To do this: Double-click on the .qmlproject file to start the new Qt Creator. Click on Tools->Options…, click on Kits, click on Qt 5.3.1, then click on Make Default. In each .qml source file, change the line: import QtQuick 1.1 to: import QtQuick 2.0 Click on File->Save All, then exit Qt Creator. Delete the .qmlproject.user file in your project folder – this removes any incorrect project settings (which are based on old file contents). Double-click on the .qmlproject file to start Qt Creator with the new settings.
I made a QML project that worked. When I try to reopen, I get File Not Found error.
If you are getting the error “file:///C:/Users/…/project.qml: File not found”, double-check the file path in settings.json to see if it is correct. It is created with the original pathname, so if you change any folder names in the path, then Qt will not be able to find the files.
