How to create a sketch area in a ui window

Question

My requirement.

What I tried in Qt 5.15?

My Question: How to create sketch area in the layout window so that there is sketching space and space for my sketching features? Can anyone help with this? I hope my question is clear.

Answer 1

you need to play with the layout properties... specifically the layoutstretch

if you set that to 1,5 the left widget is taking space in a ration 1:5 to the right widget...

Answer 2

1.First of all, I put all your TabWidget in centralwidget with 2 tabs Tab1 and Tab2 like this :

2. I go to this and change the maximum size to 200 this is l1.

3.set GridLayout For centralwidget and add one widget near Tabwidget.

you can set maximum width of widget to 1000.as l1*5.

4.put pushbuttons in tab1 and I set Vertical layout for Tab1 .

this UI code you can copy+past it in your UI file and use it.
