ui widget erro:warning

[saman_artorious]

I am creating some new Dialogue boxes in my project using ui designer. When I run the project, I get the following
error:warnings:

dialog_cam_wd.ui:-1: error: Warning: Z-order assignment: 'gridLayoutWidget' is not a valid widget.
dialog_cam_wd.ui:-1: error: Warning: Z-order assignment: 'horizontalLayoutWidget' is not a valid widget.
dialog_cam_wd.ui:-1: error: Warning: Z-order assignment: 'horizontalSpacer' is not a valid widget.

dialog_cam_wd.ui:-1: error: Warning: Z-order assignment: 'gridLayoutWidget' is not a valid widget.
dialog_cam_wd.ui:-1: error: Warning: Z-order assignment: 'horizontalLayoutWidget' is not a valid widget.
dialog_cam_wd.ui:-1: error: Warning: Z-order assignment: 'horizontalSpacer' is not a valid widget.

To copy to clipboard, switch view to plain text mode 

How can I fix it?

You just have to edit your ui file, delete these lines :

<zorder>gridLayoutWidget</zorder>
<zorder>horizontalLayoutWidget</zorder>
<zorder>horizontalSpacer</zorder>

Layout are not widget, that's why you can't edit order ... (eg deginer -> edit tab order ..)
