Qt QGridLayout automatically centers (moves) items to the middle.
c++, python, qgridlayout, qscrollarea, qt
Solution
There is also a method different from what trollixx answered: add a dummy widget with its vertical size policy set to expanding, at the 'bottom' of the `QGridLayout`. See this answer, which also contains an example with a toolbar.
Problem
I have a `QHBoxLayout` on my form with 3 layouts added to it. The second one has the items concerning my question. I have a `QVBoxLayout` on the second pane of the main layout (the `QHBoxLayout`). This `QVBoxLayout` has a `QScrollArea` added to it with `addWidget`. This `QScrollArea` is parent to a `QWidget` called "scrollContents" which in turn contains a `QGridLayout`. I am adding a custom created widget to this `QGridLayout` which has a fixed height. We can consider this `100px` for now. If this `QGridLayout` has items, of which the total height is less than the form itself, it centers these widgets vertically with same amount of space between them. If there is one single widget, it appears right in the middle. But I would like them to be listed from top to bottom. Ex.: [### represents the area of `QScrollArea` in which there's a `QWidget` with the `QGridLayout`. ``` OK -> DESIRED -> NOT DESIRED AND WHAT HAPPENS ########## ########## ########## # |item| # # |item| # # # # |item| # # # # # # |item| # # # # # # |item| # # # # |item| # # |item| # # # # # # |item| # # # # # # |item| # # # # # ########## ########## ########## |item| |item| |item| ``` Basically: If there's space for 9 "rows", when a single one item is added it appears in the middle at the location of 5th. If there is 9 or more, they appear as they should. If there is 8 or less, their space in-between is expanded to center them all. How can I solve this? Thank you.
