Hello everyone,
I am writing a script that will allow me to automate the layout grid construction process in InDesign. For the moment I have implemented 2 or 3 construction methods and now I am focusing on the interface through which I can modify custom parameters.
The problem is that it seems impossible to execute a function upon pressing a button in the dialog.
I attach the test code for reference.
var doc = app.activeDocument;
var masterIndex = 0;
var master_spread_left = doc.masterSpreads.item(masterIndex).pages.item(0);
var master_spread_right = doc.masterSpreads.item(masterIndex).pages.item(1);
var pageHeight = Math.round(doc.documentPreferences.pageHeight);
var pageWidth = Math.round(doc.documentPreferences.pageWidth);
var pageRatio;
if (pageHeight >= pageWidth) {
pageRatio = pageWidth / pageHeight;
} else if (pageWidth > pageHeight) {
pageRatio = pageHeight / pageWidth;
}
var marginTop, marginBottom, marginLeft, marginRight;
var marginRatio = 1 - pageRatio;
gridWizardDialog();
function gridWizardDialog() {
var myDialog = new Window ('dialog {text: "Grid Wizard", orientation: "column", alignChildren: ["fill","fill"], properties: {closeButton: false}}');
myDialog.main = myDialog.add ('group {preferredSize: [600, 500], alignChildren: ["left","fill"]}');
myDialog.subTabs = myDialog.main.add ('listbox', undefined, ['Everything Everywhere All At Page Ratio', 'Gutenbergify', 'I Kissed A Square And I Liked It']);
myDialog.tabGroup = myDialog.main.add ('group {alignment: ["fill","fill"], orientation: "stack"}');
myDialog.tabs = [];
//1 - Everything Everything Everywhere All At Page Ratio
myDialog.tabs[0]= myDialog.tabGroup.add('group');
myDialog.tabs[0].add('statictext{text: "Everything Everywhere All At Page Ratio"}')
myDialog.tabs[0].add('panel');
// Full - Empty Area Ratio
var everythingEverywhereAllAtPageRatioMarginRatioGroup = myDialog.tabs[0].add('group');
everythingEverywhereAllAtPageRatioMarginRatioGroup.orientation = 'row';
everythingEverywhereAllAtPageRatioMarginRatioGroup.add('statictext{text: "Full - Empty Area Ratio:"}');
var myMarginRatioField = everythingEverywhereAllAtPageRatioMarginRatioGroup.add('edittext', undefined, marginRatio.toFixed(2), {multiline: false, wantReturn: false});
myMarginRatioField.characters = 4;
myMarginRatioField.enabled = false;
var myMarginRatioCheckbox = everythingEverywhereAllAtPageRatioMarginRatioGroup.add('checkbox', undefined, 'set a custom value');
myMarginRatioCheckbox.onClick = function() {
myMarginRatioField.enabled = myMarginRatioCheckbox.value;
};
// Columns number
var everythingEverywhereAllAtPageRatioColumnsGroup = myDialog.tabs[0].add('group');
everythingEverywhereAllAtPageRatioColumnsGroup.orientation = 'row';
everythingEverywhereAllAtPageRatioColumnsGroup.add('statictext{text: "Number of columns:"}');
var myColumnsNumberField = everythingEverywhereAllAtPageRatioColumnsGroup.add('edittext', undefined, '1');
myColumnsNumberField.characters = 4;
for (var i = 0; i < myDialog.tabs.length; i++) {
myDialog.tabs[i].orientation = 'column';
myDialog.tabs[i].alignChildren = 'fill';
myDialog.tabs[i].alignment = ['fill','fill'];
myDialog.tabs[i].visible = false;
}
myDialog.subTabs.onChange = showTab;
function showTab () {
if ( myDialog.subTabs.selection !== null) {
for (var i = myDialog.tabs.length - 1; i >= 0; i--) {
myDialog.tabs[i].visible = false;
}
myDialog.tabs[myDialog.subTabs.selection.index].visible = true;
}
}
var okButton = myDialog.add ('button', undefined, "oooook");
okButton.onClick = function(){
var myMarginRatio = parseFloat(myMarginRatioField.text);
var myColumnsNumber = parseFloat(myColumnsNumberField.text);
everythingEverywhereAllAtPageRatio(myMarginRatio, myColumnsNumber);
}
myDialog.show();
}
function everythingEverywhereAllAtPageRatio(marginRatio, columns) {
var marginWidth = pageWidth * marginRatio;
marginTop = marginHeight / 2;
marginBottom = marginHeight / 2;
marginLeft = marginWidth / 2;
marginRight = marginWidth / 2;
var columnsWidth = (pageWidth - marginWidth) / columns;
var marginHeight = pageHeight * marginRatio;
var rowsHeight = (columnsWidth * (pageHeight - marginHeight)) / (pageWidth - marginWidth);
var gutterWidth = (columnsWidth * marginRatio) / 2;
var gutterHeight = (rowsHeight * marginRatio) / 2;
for (var i = marginLeft + columnsWidth; i < pageWidth - marginRight - 1; i += columnsWidth) {
with (master_spread_left) {
guides.add(undefined, { orientation: HorizontalOrVertical.vertical, location: (i - gutterWidth / 2) });
guides.add(undefined, { orientation: HorizontalOrVertical.vertical, location: (i + gutterWidth / 2) });
}
with (master_spread_right) {
guides.add(undefined, { orientation: HorizontalOrVertical.vertical, location: (pageWidth + i - gutterWidth / 2) });
guides.add(undefined, { orientation: HorizontalOrVertical.vertical, location: (pageWidth + i + gutterWidth / 2) });
}
}
for (var j = marginTop + rowsHeight; j < pageHeight - marginBottom - 1; j += rowsHeight) {
with (master_spread_left) {
guides.add(undefined, { orientation: HorizontalOrVertical.horizontal, location: (j - gutterHeight / 2) });
guides.add(undefined, { orientation: HorizontalOrVertical.horizontal, location: (j + gutterHeight / 2) });
}
with (master_spread_right) {
guides.add(undefined, { orientation: HorizontalOrVertical.horizontal, location: (j - gutterHeight / 2) });
guides.add(undefined, { orientation: HorizontalOrVertical.horizontal, location: (j + gutterHeight / 2) });
}
}
master_spread_left.marginPreferences.properties = {
right: marginRight,
top: marginTop,
left: marginLeft,
bottom: marginBottom,
};
master_spread_right.marginPreferences.properties = master_spread_left.marginPreferences.properties;
doc.pages.item(0).appliedMaster = doc.masterSpreads.item(0);
}
While trying to debug, I noticed that if I insert inside okButton.onClick = function(){ } an alert(), it is correctly displayed, but if instead I insert the function everythingEverywhereAllAtPageRatio(), nothing happens. I also tried manually specifying the parameters of everythingEverywhereAllAtPageRatio() (without calling them from the editboxes in the interface) and the problem still occurs.
I thank in advance anyone who can help me out.
