This interface can be implemented by widgets which allow the user to choose a color.
Depending on the situation, colors may be allowed to have alpha (translucency). The main widgets that implement this interface are ColorChooserWidget, ColorChooserDialog and ColorChooserButton.
- Since gtkmm 3.4:
Adds a palette to the color chooser.
If orientation is horizontal, the colors are grouped in rows, with colors_per_line colors in each row. If orientation is vertical, the colors are grouped in columns instead.
The default color palette of ColorChooserWidget has 27 colors, organized in columns of 3 colors. The default gray palette has 9 grays in a single row.
The layout of the color chooser widget works best when the palettes have 9-10 columns.
Calling this function for the first time has the side effect of removing the default color and gray palettes from the color chooser.
- Parameters
-
orientation | ORIENTATION_HORIZONTAL if the palette should be displayed in rows, or ORIENTATION_VERTICAL for columns |
colors_per_line | The number of colors to show in each row/column. |
colors | The colors of the palette. |
