Eto OnOKButtonClick custom argument

user1332 · February 14, 2022, 11:36pm

Good day,

I am working with Eto Forms. My goal is to have an interactive dialog that allowed to rotate different objects in Rhino.

After creating a series of buttons with a for loop:

I wish for every button to perform a rotation on a different element when its click on. So I thought about creating a method that takes i from the for loop as argument, something like this:

Nevertheless I am running into several errors while trying this method. I am thinking that the functions for onclickactions are only limited to three arguments (self, sender, e). Is this correct? or is there another way to allow to add arguments.

Thanks for your help

Juan

Set the Control.Tag Property on your Button and check it in your click handler.

I use that in Advanced Render Settings panel like so

github.com

mcneel/RhinoCycles/blob/1afca509b08b3bbe27d2dfb7fd0ec996e0d4b1f0/Settings/AdvancedSettingsSection.cs#L157

      
        
            				VerticalAlignment = VerticalAlignment.Center,
            			};
            
            
			StepperSeed = new NumericStepper()
            			{
            				Value = 0,
            				MaxValue = int.MaxValue,
            				MinValue = 0,
            				MaximumDecimalPlaces = 0,
            				Width = 75,
            				Tag = AdvancedSettings.Seed,
            			};
            
            
			LblSamples = new Label()
            			{
            				Text = Localization.LocalizeString("Samples", 6),
            				VerticalAlignment = VerticalAlignment.Center,
            			};
            			StepperSamples = new NumericStepper()
            			{
            				Value = 0,

            			StepperMaxTransmissionBounces.ValueChanged -= IntegratorSettingValueChangedHandler;
            			StepperMaxTransparencyBounces.ValueChanged -= IntegratorSettingValueChangedHandler;
            		}
            
            
		private void IntegratorSettingValueChangedHandler(object sender, EventArgs e)
            		{
            			var vud = Settings;
            			if (vud == null) return;
            
            
			if (!(sender is NumericStepper ns)) return;
            			var setting = (AdvancedSettings)ns.Tag;
            
            
			switch (setting)
            			{
            				case AdvancedSettings.Seed:
            					vud.Seed = (int)ns.Value;
            					break;
            				case AdvancedSettings.Samples:
            					vud.Samples = (int)ns.Value;
            					Samples = (int)ns.Value;
            					break;

You should be able to do something similar in Python for your case.

Thanks for your reply, Nathan.

The Control.Tag property is a great idea. I am working with it as follows:

And later in the click handler I am cheking its value like this:

When testing in Rhino, every time I click on the buttons I get the same number printed (the max of the range function).

Would you know a way, on how to get set a different value for the tag of each button, I have the feeling it is getting overwrite in the for loop.

Thanks again

You are creating num_elements buttons all in the same self.rotate variable. You should make self.rotate a list if you want to keep many numbers. But that still won’t help in the click handler.

Instead, you should look at sender, not self.rotate, in your click handler. That should be your Button, and will have the Tag property with the value you are looking for.

Amazing! it is working like a charm.

in case somebody else wants to follow the workflow:

When testing, after pressing each button I am able to print the i index associate with the Control.

Many many thanks,
Juan
