Application Settings - Working with Pop-up Windows

Only for the Trident Engine

The Chromium engine handles pop-up windows itself. The following topic is only for applications running with the Trident engine.

ExeOutput for PHP lets you open several windows called pop-up windows (or popups) in the same application; thus your users can see additional information without navigating away from the current page in the main window. Popup windows are windows without toolbar or status bar. They can feature a custom menu bar however.

Each popup has a unique name.

Default Pop-up Properties

Pop-up windows can be created with different methods as explained below and you can define default properties for them here.

1BULLET You may define the default size for new pop-up windows: enter the desired width and height in the different fields. You may also click the Auto-Sizer button: it will display a small window that you can resize as you want, then ExeOutput for PHP will automatically set the window's height and width according to the size you have chosen.

1BULLET Do not manage popup Z order automatically

By default, pop-up windows are created as children of the main window. Consequently, you cannot return to the main window before closing the pop-up window. If you want to create independent pop-up windows, then enable this option.

1BULLET Include a menu bar for each pop-up

Pop-up windows may have their own menu bar with specific commands like Print, Close or custom ones. Enable this option and click Edit Menu Bar Items to manage the menu's entries.

You can call some script commands from the default Global and Macros scripts that contain commands useful for popup menus:

Global.HEExitapplication: exits the application.
Global.HECloseCurrentPopup: closes the active pop-up.
Global.HEPopupPrintPreview: shows the print preview for the current pop-up which lets end users print the contents of the pop-up window.

menu bar

Note: all pop-up windows will share the same menu bar.

How to open a popup window

There are several ways to open a new popup window from your HTML pages:

1BULLET with a standard <A HREF> hyperlink tag: use the target parameter _blank, or if you also want to assign a name to the new popup, use _hepopup_ followed by the name of your popup window (no space, alphanumeric characters only).

Note that _blank will always open a new window while _hepopup_[name] will bring the [name] window to the front if the latter already exists. For instance, click twice on the hyperlinks above.

You can also use external links like
our website

1BULLET with JavaScript functions: and window.external.ShowPopup are supported.

  • Open a popup with


myexample.txt,"popup2","width=500, height=200"); will only take account of the “width” and “height” parameters if available. If you want to set the position too, use window.external.ShowPopup instead.

Note that you should always give a name to the popup window you create with

  • Open a popup with window.external.ShowPopup

Syntax for window.external.ShowPopup:

function window.external.ShowPopup(Name, URL, Width, Height, Top, Left, Param);

Name: name of your popup window.
URL: url to the page that should be displayed. It can be a virtual path to a compiled page or a full URL. Relative paths are not handled.
Width, Height: width and height of the popup window (in pixels).
Left, Top: x and y screen coordinates of the top-left corner (in pixels).
Param: blank or one creation parameter parentexplicit or parentismain or noresize

  • parentexplicit: makes the popup independent (ignores the z-order auto management set by the option named “Do not manage popup Z order automatically”).
  • parentismain: the popup is a child of the main window, and not the window with the page or script that opened it.
  • noresize: does not allow the end user to resize the popup window.

Note: to create a screen-centered popup, set both Left and Top to -1.

All parameters are required.

1BULLET with HEScript: an internal HEScript procedure Showpopup is available and lets you specify additional parameters for your popup window.

procedure ShowPopup(const Name, URL: String; Width, Height,
 Top, Left: Integer; IsModal, RedirectLinksToMain: Boolean);

Name: name of your popup window.
URL: url to the page that should be displayed. It can be a virtual path to a compiled page or a full URL.
Width, Height: width and height of the popup window (in pixels).
Left, Top: x and y screen coordinates of the top-left corner (in pixels). If both set to -1, the popup appears centered.
IsModal: always set the value to false.
RedirectLinksToMain: whether you want the popup window to redirect all hyperlinks to the main window (when a user clicks a link, the page is displayed in the main window). Could be useful for website contents.

Example: you could associate the following procedure (ShowFirstPopup) with a custom menu command or a toolbar button.

procedure ShowFirstPopup;
 ShowPopup("mypopup", "popup1.htm", 400, 300, 50, 25, false, false);

Note: ShowPopupEx exists too.

Additionally you could add the following HEScript commands to your UserMain script:

{ NewWindow: opens a new popup window. URL : url to the page to display WindowName: name of the popup (for targets and other functions). width: width of the popup height: height of the popup top: y screen position of the popup left: x screen position of the popup redirect: if “1”, then all links are redirected to the main window. }

procedure NewWindow(Url, WindowName, Width, Height, Top, Left, Redirect: String);
ShowPopup(WindowName, Url, StrToInt(width), StrToInt(height), StrToInt(top),StrToInt(left), false, Redirect = "1");

In that case, you can now display any popup you want without having to create a specific HEScript function for each popup.
To call the previous NewWindow function from your HTML pages, use:

<a href="hescript://UserMain.newwindow|popup1.html|pop1|200|100|50|80|0">Open a new window</a>

How to close a popup window

1BULLET If you wish to close the popup window from the popup itself, you can use:

  • window.close (JavaScript):

End users may be prompted by Internet Explorer if they want to close the window.

  • window.external.CloseCurrentWindow (JavaScript):

Contrary to the previous one, this function does not ask end users whether they want to close the popup window.

1BULLET If you wish to close any popup, use window.external.ClosePopup(name) (JavaScript). You just need to know the popup's name (that can be retrieved with the JavaScript property).

Example: Open the popup / Close the popup

This function also exists in HEScript:

procedure ClosePopup(const Name: String);

1BULLET To close all popup windows, use the HEScript function CloseAllPopups.

procedure CloseAllPopups;

How to modify a popup size/position, set the focus...

You can set up properties for popup windows using the SetUIProp function (available as HEScript or window.external JavaScript extension).

JavaScript Syntax:

window.external.SetUIProp('popup_[name]', 'property name', 'property value');

Available property names are Left (x position), Top (y position), Width, Height, Caption (window title).

Example: we want to move an existing popup to another location. We can use this JavaScript code:

function setpopupxpos() {

2BULLET You can also take a look at the window.external.SetPopupProp method to set the focus, bring to front / send to back…
