Break Layout broken ?

David King

Hi mrjj,

Thank you very much for your reply, much appreciated.

Well, I'm really new to Qt, just a few days, so I can't really say about matters working differently in the past.

I've only every seen the behaviour as described in my 2 posts to this thread.

Sounds like I need to give boxgrids a try.

I also have a related issue, per my 'Break Layout broken 2' post. Would you have any insights on that maybe ?

Must admit, I find the Qt requirement to have to 'Break Layout' to add elements a bit frustration. But maybe layout managers in other products are similar.

Best regards,

David

You don't need to break a layout to add a new item.

Just drag the new item onto your existing layout, and the item will be inserted into the layout.

mrjj

adding to @JKSH , when dragging over a layout, it shows a blueline to
show where it will be inserted if dropped.

Ah, but only for 'leaf' items, within a layout.

But which I mean, I can copy Widget 2, and paste onto Horz Layout fine:

Horz Layout
Widget 1
Widget 2

I then get:

Horz Layout
Widget 1
Widget 2
Widget 2_2

But if I have eg the following, I can't copy Vert Layout, and paste onto Horz Layout:

Horz Layout
Vert Layout
Widget 1
Widget 2

So I can't get the following.

Horz Layout
Vert Layout
Widget 1
Widget 2
Vert Layout_2
Widget 1_2
Widget 2_2

At least, not without doing a Break Layout on Horz Layout first, to give me:

Vert Layout
Widget 1
Widget 2

I can then copy-paste Vert Layout, to give me:

Vert Layout_2
Widget 1_2
Widget 2_2

I can then multi-select Vert Layout, and Vert Layout_2, and choose layout horizontally, to reinstate the layout.

Problem is, after doing the above, my layout is broken, with all my Horz Layouts (I have 4 so far), laying on top of one other, all at the top of the QDialog.

How do I know that Break Layout is needed in the scenario described ?

Because Qt tells me so, via a dialogue it displays, saying that I need to do a Break Layout as described

On my list, to give boxgrids a try, to see if I get better mileage with..

Best regards,

David

Hi
If you want to clone existing layouts ( to get more)
Hold down CTRL and drag to clone the selection. (layout and all)

David King

Ah, the forum has removed my indenting. Hope makes sense still. Intention was eg:

Horz Layout
indent Vert Layout
indent indent Widget 1
indent indent Widget 2

Ie, nested layouts

mrjj

Hi
You can drag the layouts with CTRL

Yo !
Thank you so much mrjj for CTRL drag !
I had to be careful I dropped in the right place, but it worked :-)
I'm sure CTRL drag mention is somewhere in the excellent Qt documentation

@David-King
One thing i was like 2 years to discover.
You can drag a selection from the Form to the Widget list.
And then you can have it there as template. ( in the left side list, bottom)

David King

Thanks for the tip !

So is this post SOLVED I wonder ?
Well it's worked around, for sure, with CTRL-drag

Still seems buggish that the layout is broken by a Break Layout, then a reversing of that

mrjj

@David-King
Well, depending on what you put in layout and kind of stuff will happen
when you break it.
It could be a bug but it does sounds normal to me.
The red layouts might become the size of what ever is it them and its minimumsize etc.
