Hello, I'm experimenting with an XML slider UI to save the slider numerical value and slider control position. How do you save the position of the slider bar so that it corresponds to the box's numeric value?
var w = new Window("dialog","test",undefined,{closeButton: true});
var group1 = w.add("group");
var slider1 = group1.add("slider");
slider1.minvalue = 0;
slider1.maxvalue = 100;
slider1.value = 0;
slider1.preferredSize.length = 195;
slider1.preferredSize.height = 15;
var edittext1 = group1.add("edittext",undefined,"0");
edittext1.preferredSize=[50,20];
ok = group1.add("button", undefined, "Set", { name: "set" })
cancel = group1.add("button", undefined, "Close", { name: "close" })
slider1.onChanging = function(){
edittext1.text = this.value;
};
settingsSlider1 = { textItemOne: edittext1}
ok.onClick = function () {
w.close()
saveToXML(settingsSlider1, 'SliderControlSettings')
}
cancel.onClick = function () {
w.close()
}
w.onShow = function () {
readFromXML(settingsSlider1, 'SliderControlSettings')
}
w.show();
function saveToXML(o, xmlName) {
var f = new File(Folder.desktop + '/' + xmlName + '.xml'),
myXML = new XML('<variables></variables>');
for (var a in o) {
switch (o[a].type) {
case 'edittext': myXML[a] = o[a].text; break;
case 'checkbox': myXML[a] = o[a].value; break;
case 'radiobutton': myXML[a] = o[a].value; break;
case 'dropdownlist': myXML[a] = o[a].selection ? o[a].selection.text : ''; break;
}
}
f.encoding = "UTF8"
f.open('w');
f.write(myXML.toXMLString())
f.close();
}
function readFromXML(o, xmlName) {
var f = new File(Folder.desktop + '/' + xmlName + '.xml');
f.encoding = "UTF8";
f.open('r');
var myXML = new XML(f.read());
f.close();
for (var a in o) {
switch (o[a].type) {
case 'edittext': o[a].text = myXML[a] != '' ? myXML[a] : o[a].text; break;
case 'checkbox': o[a].value = myXML[a] != '' ? (myXML[a] == 'true' ? 1 : 0) : o[a].value; break;
case 'radiobutton': o[a].value = myXML[a] != '' ? (myXML[a] == 'true' ? 1 : 0) : o[a].value; break;
case 'dropdownlist': o[a].selection = myXML[a] != '' ? o[a].find(myXML[a]) : 0; break;
}
}
f.encoding = "UTF8"
f.open('w');
f.write(myXML.toXMLString())
f.close();
}

The text box expects a string, you have to cast all the XML values to there correct type.

This is a text script that creates an XML file and saves to the desktop. I've added a slider and edittext box control. My script uses a recursive function to gather and store all the control data in the XML file. With this you can change the UI, without having to change what is saved to the XML. The only thing you have to do is give each control a variable name, and you have to declare that name in the script. For the slider and editext controls, I've added an onChanging function to both so that

Thanks, I have the opposite issue with the sample dialog box.
The slider indicator stays on the slider bar but the numerical value does not upon closing the dialog.
The textbox displays the value of Default, and the slider numerical value is written to the XML file.
How do I get the textbox to display the numerical value on the next run of the dialog box?
The onChanging event prints the slider numerical value on the textbox.
testWindow.panel.slider1.onChanging = function(){
testWindow.panel.textbox1.text = this.value.toFixed(0);
}
Thank you both, I was able to figure out the textbox value question with your help. Here is the full Utility Pack script with the slider and adjusting textbox slider value.
