[Maya-Python] Re: fileDialog2

[Tim]

Here is one in MEL.  The UI is just copy/pasted from the frameLayout
example in the doc's, except that it tracks one of the int sliders
with an optionVar so it will remember the value it was set to last.


global proc MyOptionsUISetup(string $parent)
{
        setParent $parent;

        columnLayout -adjustableColumn true;
                frameLayout -label "Buttons"
                        -borderStyle "in";
                        columnLayout;
                                button;
                                button;
                                button;
                                setParent ..;
                        setParent ..;
                frameLayout -label "Scroll Bars"
                        -borderStyle "out";
                        columnLayout;
                                intSlider -min -100 -max 100 -value 0 -step 1 
MyIntSlider;
                                intSlider;
                                intSlider;
                                setParent ..;
                        setParent ..;
                frameLayout -label "Fields"
                        -borderStyle "etchedIn";
                        columnLayout;
                                intField;
                                intField;
                                intField;
                                setParent ..;
                        setParent ..;
                frameLayout -label "Check Boxes"
                        -borderStyle "etchedOut";
                        columnLayout;
                                checkBox;
                                checkBox;

                                setParent ..;
