jQuery dialog: how to control the button-pane height

Question

How do I manually adjust/set the height of the button-pane in the jQuery dialog without changing the CSS file? I want to adjust the height of the DIV that contains the message and the DIV that contains the button(marked in green lines) from Javascript.

function showMessageDialog(title, message, width){
     // create div if it doesn't exist already
     if(!$("#msgDialogDiv").length) {
         $("<DIV></DIV>").appendTo("body").attr("id","msgDialogDiv");
     }
     // set the message
     $("#msgDialogDiv").html(message).css("color","red");

     // show the dialog
     $("#msgDialogDiv").dialog({
        modal: true, resizable: false, draggable: false, title: title, width: width,
        buttons: {OK: function(){$(this).dialog("close");}}
      });

      // This changes the height as I want.
      // $("#msgDialogDiv").css({"overflow":"hidden","height":"10px"});
      // this changes the font on button
      //$("#msgDialogDiv").dialog("widget").find(".ui-button-text").css("font-size", "11px");
      return;
}

showMessageDialog("Hello Stackoverflow!", "This is my first question on stackoverflow",400);

While posting this question I tried to adjust the DIV height and it worked. I also tried changing the font-size of the button, but that just changes the size of the button. I want to control the size of that entire DIV. Is it due to the padding around the button?

Answer 1

Found it myself. This is what I was looking for.

// set the size of the button
$("#msgDialogDiv").dialog("widget")
                  .find(".ui-button-text").css("font-size", "10px")

// this is not required. but doesn't hurt. To hardcode the height, 
// just change to height instead of minHeight
//$("#msgDialogDiv").css({"minHeight":"10px"})

// button pane style
$("#msgDialogDiv").dialog("widget").find(".ui-dialog-buttonpane")
                  .css({"padding":".1em .1em .1em 0","margin":"0 0 0 0"} )

// button style
$("#msgDialogDiv").dialog("widget").find("button")
                  .css({"padding":"0 .2em 0 .2em","margin":"0 .5em 0 0"} )
