Once again, go to the "Additional" part Page, select a "bitbtn" button (the icon is an OK button with a green check mark), and put it underneath the other three button parts.

Click the Dialog tab, select the ColorDialog part that makes the icon in a 16-color grid, and place it anywhere on the form. Because this part is not a visual part, so its position does not affect the overall situation.

Adjustment and alignment of 1.2.3.2 parts

In general, the parts that are placed on the form are distributed, and their size is not the size that is really needed.

The Alignment tools and window grids provided by Delphi are convenient for these adjustments.

1. Moving Parts

To accurately describe the size of the part, on the object inspector, change the left (the pixel point of the part to the left edge of the form), top (the pixel points on the form's border to the top edge of the part), width (the width of the part itself), Height ( Properties such as the height of the part itself. As for changing the properties of a part, the following will be explained in detail.
