Display proportional value in the text box part II

[Shulipa Bernad]

Hi @Rbin, how are you? This time, how to get the correct proportional value of height or width  when modifying the values of the text box since the dialog box informs the initial values of width and height of the active layer, but layers with different sizes.

var tmp = preferences.rulerUnits; 
app.preferences.rulerUnits=Units.CM;
LB = activeDocument.activeLayer.bounds; 
L = (LB[2].value.toFixed(1))-(LB[0].value.toFixed(1)); 
A = (LB[3].value.toFixed(1))-(LB[1].value.toFixed(1));  

dlg = new Window("dialog"); dlg.text = "Dialog";
dlg.orientation = "row"; dlg.alignChildren = ["center","center"];
dlg.spacing = 10; dlg.margins = 16;

et1 = dlg.add('edittext {properties: {name: "et1"}}');
et1.text = L;

st1 = dlg.add("statictext", undefined, undefined, {name: "st1"});
st1.text = "x";

et2 = dlg.add('edittext {properties: {name: "et2"}}');
et2.text = A;

st2 = dlg.add("statictext", undefined, undefined, {name: "st2"});
st2.text = "cm ";

et1.onChanging = function(){ et2.text = Number(et1.text)*1.5};
et2.onChanging = function(){ et1.text = Number(et2.text)/1.5};

dlg.show();

preferences.rulerUnits= tmp

I don't know what the initial condition of the problem was (why @r-bin  used a fixed coefficient of 1.5), but if I understood correctly, then this code will work as you need:

var tmp = preferences.rulerUnits; 
app.preferences.rulerUnits=Units.CM;
LB = activeDocument.activeLayer.bounds; 
L = (LB[2].value.toFixed(1))-(LB[0].value.toFixed(1)); 
A = (LB[3].value.toFixed(1))-(LB[1].value.toFixed(1));  

dlg = new Window("dialog"); dlg.text = "Dialog";
dlg.orientation = "row"; dlg.alignChildren = ["center","center"];
dlg.spacing = 10; dlg.margins = 16;

et1 = dlg.add('edittext {properties: {name: "et1"}}');
et1.text = L;

st1 = dlg.add("statictext", undefined, undefined, {name: "st1"});
st1.text = "x";

et2 = dlg.add('edittext {properties: {name: "et2"}}');
et2.text = A;

st2 = dlg.add("statictext", undefined, undefined, {name: "st2"});
st2.text = "cm ";

et1.onChanging = function(){ et2.text = Number(et1.text)/L*A};
et2.onChanging = function(){ et1.text = Number(et2.text)/A*L};

dlg.show();

preferences.rulerUnits= tmp 

P.S. I hope if we mention @r-bin often enough, he will come 😄

Hello @jazz-y  man you are a genius! I confess I didn't expect the solution so quickly. Thanks.

It looks like correct version of first part: Display proportional value in the text box

That's right!
