When High DPI Aware is selected in Preferences - Display tab and the application size is greater than 100%, forms will be displayed differently to how they are shown at 100%. When designing forms, it is important to consider the way forms will be displayed at a larger size.
Scroll Box and Splitter Bar components can be used to ensure entire forms can be seen at a larger size.
Scroll boxes can be placed on forms to ensure entire areas can be scrolled to. Place a scroll box on a form or panel, then set the Alignment to alClient to fill the form or panel it is placed on. When components are placed on the scroll box, they will always be accessible via the scroll bar.
You can also use Splitter Bars to separate panels or scroll boxes. Splitter bars allow you to resize areas on a form, so you can view the components you need at any screen size. Place a container component, such as a Scroll Box, with Alignment set to alLeft or alTop. Then place a Splitter Bar after the component, with the same alignment. Next place another container component after the Splitter Bar, with the same Alignment or with the Alignment set to alClient. Alignment of alClient will fill the remaining space. When you run the form, you will be able to resize the container components by clicking and dragging the Splitter Bar. When forms are displayed at a higher size than 100%, information can be cut off. Using Splitter Bars allows you increase the size of a container component to show more information.
Note: The order you place container components and splitter bars is very important. Splitter bars can be linked to the component placed immediately before the splitter is placed. Make sure the parent component for the splitter and the container components is selected when you place a splitter bar.
