item could not be created please help me

mkdir

I updated to qt creator 12, but the screen does not appear because “item could not be created.” Please tell me how to fix the problem.

@mkdir did this work prior to your upgrade to Creator 12.0?

I just enabled the Designer plugin, opened a .qml file, and it promptly crashed. It might still be something of a WIP.

But, what does your CMakeLists.txt and main.cpp files look like?

mkdir

@mzimmers

cmakelist looks like this and maincpp looks like this.

mzimmers

@mkdir does your application run? I have a very similar minimal application, and get the same error in Design Mode, but the app works. I suspect it's a bug in the Design code.

mkdir

@mzimmers
And it worked well before upgrading to QT Creator 12.
So how can I fix this? Is there another way? I'm sorry because this is my first time experiencing something like this.

mzimmers

@mkdir well, if I'm correct (and it's quite possible I'm not), there's nothing to do except submit a bug report.

I'm sorry I'm not more help, but I've never used the Design tool for QML, because I found it slow and buggy. Someone else may chime in with a better answer.

mkdir

@mzimmers
thank you so much for the reply.
then which design tool is best to use for qml?

mzimmers

@mkdir again, I don't want to sound like an expert in this area, but I just code my QML in the text editor. Back when I worked with widgets, I used the design tool a lot more, but I haven't done anything with it and QML.

If no one says anything to the contrary, I would recommend submitting a bug report. If nothing else, someone should tell you what you might be doing wrong.

I have the some issue....did you solve it? I have read and tried various ways but nothing......

Any suggestions?

@Xelap
No, I recently upgraded to Qt creator 12.0.1 and it is not fixed yet. And I tried many ways, but I couldn't fix it.
