GUI Tips¶
To group items together use a container like a QFrame, QGroupBox or a QTabWidget.
If the contents of a container are rows and columns after adding at least one widget right click and select Layout > Lay Out in a Grid. Now you can drag and drop widgets into the container. The blue line or red box indicate where it will be placed.

When using a grid layout for items that may change like Dro labels change the text to represent the longest number including a minus sign if it could be displayed. Next in the property editor look at the Width and select (I usually use the column title) a widget and set the minimum width a tad bigger than the widest widget in that column. This will prevent the column from resizing as the values change.
For example the numbers in the Actual column can contain up to 8 characters like -23.4567. In the next image no mininum width has been set

All the cells in the colum will have the same width here you can see it has a width of 44

If we double click in the label and add -23.4567 the width changes to 61.

I usually set the title of a column width to be a bit wider than the widest widget in the column.

If you drag a container into another container that has a layout and it’s real short just set the minimum height to make it larger and easier to drag and drop into.
Ctrl + left click to select several widgets to change properties.
The Monospace font is good for numbers that need a fixed width.
