This is because when e.g a vertical layout is shown in its minimum height all its child items will consequently also have their minimum height. Note that, whether they become exactly 1/3 and 2/3 of the available space depends on their size hints. By default, two identical items arranged in a linear layout will have the same size, but if the first item has a stretch factor of 1 and the second item has a stretch factor of 2, the first item will aim to get 1/3 of the available space, and the second will aim to get 2/3 of the available space. This property allows you to specify the vertical stretch factor. The default value is -1, which means that no stretch factor is applied. As a consequence of this, stretch factors will only determine the growth rate of child items between the preferredWidth and maximumWidth range. This strategy is applied regardless of what the individual stretch factors are. Likewise, when a horizontal layout has its preferred width, all child items will have their preferred widths, and when a horizontal layout has its maximum width, all child items will have their maximum widths. This is because when e.g a horizontal layout is shown in its minimum width all its child items will consequently also have their minimum width.

This property allows you to specify the horizontal stretch factor. If there are multiple items with fillWidth (or fillHeight) set to true, the layout will grow or shrink the items relative to the ratio of their preferred size.įor more details on the layout algorithm, see also the Qt Quick Layouts Overview. Otherwise, it will grow or shrink between its minimum and maximum size as the layout is resized.

If they are false, the item's size will be fixed to its preferred size. The fillWidth and fillHeight properties can either be true or false. If maximum size has not been explicitly specified on an item, the size is set to Number.POSITIVE_INFINITY.įor layouts, the implicit minimum and maximum sizes depend on the content of the layouts. If minimum size has not been explicitly specified on an item, the size is set to 0. Due to this, items have a minimum size, preferred size and a maximum size. When a layout is resized, items may grow or shrink. The properties of the attached object influence how the layout will arrange the items.įor instance, you can specify minimumWidth, preferredWidth, and maximumWidth if the default values are not satisfactory.
