Help with the simple script - keyboard input
Can you assist me with this script? My goal is to keep a textbox always highlighted. Additionally, when I press the "W" key on my keyboard, I want to delete all the content in the textbox, add the composition width to the textbox, and highlight all the text in the box, so that when I start typing I can easily change and delete all the numbers.
However, I am encountering a problem with the "textOnChanging()" function. The numbers that appear in the textbox are only zeros, and I'm unsure how to highlight the text properly.
Here is the code:
{
function template(thisObj)
{
var scriptName = "template1";
function BuildAndShowUI(thisObj)
{
// Create and show a floating palette.
var my_palette = (thisObj instanceof Panel) ? thisObj : new Window("palette", scriptName, undefined, {resizeable:true});
if (my_palette != null)
{
var res =
"group { \
orientation:'column', alignment:['fill','top'], alignChildren:['left','top'], spacing:5, margins:[0,0,0,0], \
introStr: StaticText { text:'Template:', alignment:['left','center'] }, \
optsRow: Group { \
orientation:'column', alignment:['fill','top'], \
widthButton: RadioButton { text:'New Comp Width', alignment:['fill','top'], value: 'true' }, \
heightButton: RadioButton { text:'New Comp Height', alignment:['fill','top']}, \
text_input: EditText { text:'1.0', alignment:['left','top'], preferredSize:[80,20], active: true }, \
}, \
cmds: Group { \
alignment:['fill','top'], \
okButton: Button { text:'Run', alignment:['fill','center'] }, \
}, \
}";
my_palette.margins = [10,10,10,10];
my_palette.grp = my_palette.add(res);
my_palette.addEventListener('keydown', keyPressed);
my_palette.grp.optsRow.text_input.onChanging = textOnChanging;
my_palette.grp.optsRow.text_input.text = firstInputTextValue();
my_palette.grp.optsRow.text_input.active = true;
my_palette.onResizing = my_palette.onResize = function () {this.layout.resize();}
return my_palette;
}
}
function firstInputTextValue() {
var activeItem = app.project.activeItem;
var textInsideBox1;
if ((activeItem == null) || !(activeItem instanceof CompItem)) {
} else {
textInsideBox1 = activeItem.width;
}
return textInsideBox1;
}
function textOnChanging() {
var enteredValue = my_palette.grp.optsRow.text_input.text;
if (isNaN(enteredValue) || (enteredValue < 0)) {
my_palette.grp.optsRow.text_input.text = "0";
};
}
function keyPressed() {
var myKeyState = ScriptUI.environment.keyboardState;
try {
switch (myKeyState.keyName)
{
case "W":
my_palette.grp.optsRow.widthButton.value = true;
my_palette.grp.optsRow.text_input.text = inputText();
break;
case "H":
my_palette.grp.optsRow.heightButton.value = true;
my_palette.grp.optsRow.text_input.text = inputText();
break;
case "Escape": my_palette.close(); break;
}
} catch (err) {}
}
function inputText() {
var activeItem = app.project.activeItem;
var textInsideBox;
if ((activeItem == null) || !(activeItem instanceof CompItem)) {
} else {
if (my_palette.grp.optsRow.scaleButton.value) {
textInsideBox = 1.0;
}
else if (my_palette.grp.optsRow.widthButton.value) {
textInsideBox = activeItem.width;
}
else if (my_palette.grp.optsRow.heightButton.value) {
textInsideBox = activeItem.height;
}
else {}
}
return textInsideBox
}
var my_palette = BuildAndShowUI(thisObj);
if (my_palette != null) {
if (my_palette instanceof Window) {
my_palette.center();
my_palette.show();
} else {
my_palette.layout.layout(true);
my_palette.layout.resize();
}
} else {
alert("Could not open the user interface.", scriptName);
}
}
template(this);
