Description

My poor English...let me try...hope you can understand...

This bug was found in version 4.8.5  & 5.9.0 at working place，and 5.2.0 at home.Sometime you compile a ui file, it may waring " zorder assignment is not a valid widget ", because some items which are not widgets in ui file have zorder info.

Scene restoration: Here is a effective way to restoration.First we create a new blank widget,then put two widgets on it.we name them "widget_A"and"widget_B",i.e we have a new widget with "widget_A" and "widget_B" on it, neither of them has layout. Now we put another one item, maybe a widget or spacer or something on "widget_A", so we just call it "C", and drag "C" to "widget_B". Then call undo("C" backs to "widget_A"), and drag "C" to "widget_B" again(or we can call redo).Just repeat the step any number of times.Finally, we save this file, if "C" is spacer, we should give a layout to content("widget_A" or "widget_B", based on where is "C" layed on) before saving.Now we will find some " zorder " if we open this file in text mode.Also if "C" isn't a widget, there wiil be some warings like " zorder assignment is not a valid widget ".

Reason: The "C", we put into widget, can cause redo function when it was dragged to "widget_B" or we call action "Redo", can cause undo function when we call action "Undo".As we know, redo should turn to new state, and undo turns back.But, in this situation, something was wrong here.

Issue code: Here is a file named qdesigner_command.cpp in Src of Qt Designer.A Class named  ReparentWidgetCommand , let's have a look at its function redo & undo:

From what I understand, this class is about the operation of changing parent. In redo function, target("m_widget") was removed from the old " _q_widgetOrder " and " _q_zOrder ",  the other side, it was appended to the new " _q_widgetOrder " and " _q_zOrder ". Then in undo function, target("m_widget") was appended to the old " _q_widgetOrder " and " _q_zOrder "(because it has two members to note them, so just set them back).Here comes the point! We can see it removes target from the new " _q_widgetOrder ", but dose nothing with the new " _q_zOrder "!!!

Here it is what was done on " _q_zOrder " in redo function:

But in undo function:

See it?Should we insert " newZOrder.removeAll(m_widget); " between these two rows?

Originally, target always be removed from the old " _q_widgetOrder " and " _q_zOrder ", and be appended to the new " _q_widgetOrder " and " _q_zOrder " in redo function. So both " _q_widgetOrder " and " _q_zOrder " have same list.When we save file, the code checks wether they are equal or not.if they are equal, Designer will not write any " zorder " in .ui file.As mentioned above, undo can make them not eaqual, So Designer writes " zorder " in .ui file.

So I think target should be removed from both the new " _q_widgetOrder " and " _q_zOrder " in undo function.

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

Re: ui widget erro:warning

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 ..)

I'm on kubuntu

But i see on your pictures that the expression icon is not centered. Maybe a windows developer need to have a look there, such little details are very hard to get right with a platform not available.

Stuck without Qt4 in Ubuntu 20.04

I just upgraded to Ubuntu Focal Fossa and found that the lack of Qt4 means it isnt possible to build antimicro

I noticed this post saying it would work with libqt4-dev, and I'm sure would as it compiled fine on earlier versions of Ubuntu.

Is there any way to install Qt4 on Focal Fossa?

With Qt5 it reaches 100%, but fails at 100% and gives lots of errors:

Any help much appreciated!

• 1 Qt4 is EOL & unsupported upstream (2015 upstream though Debian & Ubuntu supported it until 15-Mar-2019) which is why it started to be removed entirely in 2019 in the eoan & focal cycles (refer discourse.ubuntu.com/t/… ). The app if maintained should have been ported to Qt5 (introduced 19-Dec-2012) –  guiverc Apr 28, 2020 at 4:38
• Somewhere else: ubuntuforums.org/showthread.php?t=2441709 –  DK Bose Apr 28, 2020 at 4:46
• And as suggested there, your best bet is to ask the developer or maintainer to move to qt5 . –  DK Bose Apr 28, 2020 at 4:48

It is simply available with actual Qt5 dependency in the universe pocket for focal . Install with:
