Help Button

[gionnyp9672044]

I am creating a small dialog panel

I would like to add a button with this function

you think you can do it?

this function

var aLevels = dPanel.add ("checkbox", undefined, "Apply auto levels");

if (app.documents.length > 0) {

  try {

  if (activeDocument.activeLayer.visible == true) {

  activeDocument.activeLayer.visible = false;

  } else {

  activeDocument.activeLayer.visible = true;

  }

  }

  catch (e) {}

}

Do you want a button to click or a checkbox? You have a checkbox mentioned above. To have a button run a function you would use:

var dlg = new Window('dialog','help button');
dlg.helpButton = dlg.add('button',undefined,'Help Button');
dlg.helpButton.onClick = function(){
//your function code here
dlg.close()//if you want the dialog box to close
}
dlg.show()

I would need a checkbutton

which has the dual function to enable and disable the selected level.

[tssee]

I'm still unclear about what exactly you want to do. a checkbox turns something on or off, which doesn't seem too good for the code you have listed above. If you want a button that turns a layer's viability on or off depending if that layer is visible or not then you can use code like this: add line 4 to your onClick function for a button.

var doc = activeDocument;
var layer = doc.activeLayer;

layer.visible = layer.visible == false
