Common Attributes

Integer/Double Slider

For int or double properties, a slider widget will be created. You can use the MinimumValue and MaximumValue attributes to control the range of the slider, and the IncrementValue attribute to specify the step size of the slider. For double, you can also use the DigitsValue attribute to control the number of decimal places.

public class MyEffectData : EffectData
{
    [MinimumValue(1), MaximumValue(5)]
    public int IntegerValue = 2;

    [DigitsValue(3), IncrementValue(0.1)]
    public double DoubleValue = 1.0;
};

Random Seed

If an int property is named "Seed", it will create a "Reseed" button instead of a slider. Use this if your effect requires a random value.

public class MyEffectData : EffectData
{
    public int Seed;
};

Angle Picker

If a double property is named "Angle" or "Rotation", an angle picker will be created instead of a slider.

public class MyEffectData : EffectData
{
    public double Angle;
    public double Rotation;
};

Checkbox

For bool properties, a checkbox will be created.

public class MyEffectData : EffectData
{
    public bool Invert;
};

Point Picker

For Gdk.Point properties, a widget will be created that allows the user to specify the coordinates of a point on the canvas.

public class MyEffectData : EffectData
{
    public Gdk.Point Point;
};

Offset Picker

For Cairo.PointD properties, a widget will be created that allows the user to specify an offset from the center of the canvas. The coordinates will be normalized, so that (-1, -1) is the top left corner and (1, 1) is the bottom right corner.

public class MyEffectData : EffectData
{
    public Cairo.PointD Offset;
};
