The Object Debugger is a Runtime version of the Object Inspector. The Object Debugger allows you to inspect the published properties of the components of a program at run time, and edit them. You simply place the component on the main form of your project, and when the program starts, the Object Debugger window is automatically opened.
Here is a screenshot, to give you an idea:
Select form and component you are interested in (also the form is listed among its components), and see its published properties, its events, and some mode data. Clicking on the first line shows RTTI information for the last property you've selected. Clicking on a value activates its editor (if available).
Editors include: numbers, strings, characters, enumerations, sets, cursors, colors (double-click), string lists (double click).
The only property of the component is used to set it initially "Always on Top".
