Question

JColorChooser.showDialog(tEkran, "Select a Color", selectedColorBG);

选择一种颜色后，我需要将其转移到3变量。像这样：

colorR = selectedColorBG.getR

colorG = selectedColorBG.getG

colorB = selectedColorBG.getB

有没有办法做到这一点？

Answer 1

JColorChooser有一个getColor方法，返回Color，其中分别包含方法getRed，getGreen和getBlue

Answer 2

您必须处理返回值：

Color selectedColor = JColorChooser.showDialog(tEkran, "Select the color", initialColor);
int red = selectedColor.getRed();
int green = selectedColor.getGreen();
int blue = selectedColor.getBlue();

Answer 3

查看java.awt.Color documentation会回答您的问题：

int getAlpha()
    Returns the alpha component in the range 0-255.
int getBlue()
    Returns the blue component in the range 0-255 in the default sRGB space.
int getGreen()
    Returns the green component in the range 0-255 in the default sRGB space.
int getRed()
    Returns the red component in the range 0-255 in the default sRGB space.
