dose the other column widget influnces the whole gridlayout widgets?

nicker player

I put some widgets on the qgridlayout.
row1:qlabel,qlineedit
row2:qlabel,qlineedit
row3::qlabel,qlineedit
row4:qwidget

I put the qwidget which width is wider than the qlabel.So how to set the gridlayout so that the row1 and row3'width wouldnt be changed by the row4 qwidget?
I added an extra layout on the gridlayout for the row4 qwidget.but didnt work.Heres the pic that what I want to do.the yellow part is the area of widgets,the border means different parts of widgets.

Don't really know what you mean, obviously in a grid layout the width of a column in one row will influence the width in another row. Use fixed widths and/or use a column span maybe in your row #4?

Start with a vertical layout
add a first grid layout to it
add a horizontal layout for the widget alone
add a second grid layout

The issue with that approach is that the two grid layouts are quite independent, so there is no guarantee at all that column1 will be same width in both.

@nicker-player
By all means try @mpergand's suggestion. But your row #5 could just be a two-column span, maybe you already know that.
