First, put multiple speedbutton controls in a panel, and you can define the style yourself. After I drag them out, modify their properties
parentBiDimode、parentFont、parentShowHint都为false。
Transparent is also set to false. This is to keep the speedbutton his own color
The main thing is to set the value of GroupIndex to be the same, here I set it to 1.
In this way, multiple speedButtons are realized together, and only one of them is pressed.
