Hello,
I was wondering how to update controls in a plugin.
The use case is to estimate some parameters and then let the user choose to adjust the values himself.
I my case, I have properties like that :
protected override PropertyCollection OnCreatePropertyCollection()
{
var propertyList = new List<Property>
{
StaticListChoiceProperty.CreateForEnum(PropertyNames.WhiteBalanceMethod, WhiteBalanceMethod.None, false),
new DoubleProperty(PropertyNames.RedGain, 1.0, 0.0, 2.0),
new DoubleProperty(PropertyNames.GreenGain, 1.0, 0.0, 2.0),
new DoubleProperty(PropertyNames.BlueGain, 1.0, 0.0, 2.0)
};
return new PropertyCollection(propertyList);
}
For those properties I set up the controles like that :
protected override ControlInfo OnCreateConfigUI(PropertyCollection props)
{
var defaultConfigUi = CreateDefaultConfigUI(props);
defaultConfigUi.SetPropertyControlValue(PropertyNames.RedGain, ControlInfoPropertyNames.DisplayName, "Red Gain");
defaultConfigUi.SetPropertyControlValue(PropertyNames.GreenGain, ControlInfoPropertyNames.DisplayName, "Green Gain");
defaultConfigUi.SetPropertyControlValue(PropertyNames.BlueGain, ControlInfoPropertyNames.DisplayName, "Blue Gain");
defaultConfigUi.SetPropertyControlValue(PropertyNames.WhiteBalanceMethod, ControlInfoPropertyNames.DisplayName, "White Balance Method");
var controlForPropertyName = defaultConfigUi.FindControlForPropertyName(PropertyNames.WhiteBalanceMethod);
controlForPropertyName.SetValueDisplayName(WhiteBalanceMethod.None, "None");
controlForPropertyName.SetValueDisplayName(WhiteBalanceMethod.GrayWorld, "GrayWorld");
controlForPropertyName.SetValueDisplayName(WhiteBalanceMethod.Retinex, "Retinex");
controlForPropertyName.SetValueDisplayName(WhiteBalanceMethod.YCbCr, "YCbCr");
return defaultConfigUi;
}
Then, at some point, I update the properties' values with SetPropertyValue like that :
private void UpdateProperties(PropertyBasedEffectConfigToken newToken, WhiteBalanceMethod whiteBalanceMethod)
{
var whiteBalanceFunction = GetWhiteBalanceFunction(whiteBalanceMethod);
if (whiteBalanceFunction == null)
return;
var (redGain, greenGain, blueGain) = whiteBalanceFunction(SrcArgs.Surface);
(redGain, greenGain, blueGain) = Normalize(redGain, greenGain, blueGain);
newToken.SetPropertyValue(PropertyNames.RedGain, redGain);
newToken.SetPropertyValue(PropertyNames.GreenGain, greenGain);
newToken.SetPropertyValue(PropertyNames.BlueGain, blueGain);
// XXX : How to update controls with new values ?
}
Updating the property values works, and I can read back the values with GetProperty.
However it does not update the controls in the UI and the sliders remain to the value that was already set.
How can I update the controls' value to display their properties' value ?
Thanks in advance.
