如何将Xul窗口设置为“Always On Top”？ [英] How to place a Xul window as "Always On Top"?

问题描述

我发现此文件具有以下功能：

function SetAlwaysOnTop() {
    var chkTop = document.getElementById("itmAlwaysOnTop");
    var xulWin = window.QueryInterface(Ci.nsIInterfaceRequestor)
        .getInterface(Ci.nsIWebNavigation).QueryInterface(Ci.nsIDocShellTreeItem)
        .treeOwner.QueryInterface(Ci.nsIInterfaceRequestor)
        .getInterface(Ci.nsIXULWindow);
    if(chkTop.getAttribute("checked") == "true") {
        xulWin.zLevel = xulWin.raisedZ;
    } else {
        xulWin.zLevel = xulWin.normalZ;
    }
}

我需要的部分只是：

var xulWin = window.QueryInterface(Ci.nsIInterfaceRequestor)
        .getInterface(Ci.nsIWebNavigation).QueryInterface(Ci.nsIDocShellTreeItem)
        .treeOwner.QueryInterface(Ci.nsIInterfaceRequestor)
        .getInterface(Ci.nsIXULWindow);
xulWin.zLevel = xulWin.raisedZ;

但我找不到Ci所定义的内容。知道它能是什么吗？或者任何其他关于如何设置窗口总是在顶部的想法？ （该解决方案仅适用于Windows不适合我）。

But I'm not finding what where's the Ci defined. Any idea what can it be? Or any other idea of how to set a window always on top? (that solution "just for windows" don't fits to me).

- 更新

我正在阅读 nsIWindowMediator ，其中有一些方法可以处理窗口Z顺序。但是它说这些方法应该用于c ++，而不是javascript。这意味着代码应该从XPCOM组件中使用（我应该作为XPCOM组件来打开窗口）？是否有人已经使用它可以确认？

I'm reading about the nsIWindowMediator, which has some methods to handle the window Z order. But it's saying that the methods should be used from c++, not javascript. That means the code should be used from XPCOM components (I should as XPCOM component to open the window)? Does anyone that already used it could confirm?

无论如何我还在阅读。

- -update

我已经尝试过nsIWindowMediator（带有XPCOM组件）但是当我设置Z级别时它什么也没做。

I've tried the nsIWindowMediator (with a XPCOM component) but it just does nothing when I set the Z level.

仍在寻找一种方法将窗户置于最顶层..

Still look for a way to put the window aways on top..

- 尝试使用'alwaysraised'：

test.xul：

<?xml version="1.0"?>
<?xml-stylesheet href="chrome://global/skin/" type="text/css"?>

<window width="400" height="300"
    onload="open('top.xul','GreenfoxChannelWindow','chrome, alwaysraised');"
    xmlns="http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul">

    <label value="MAIN WINDOW"/>

</window>

top.xul：

<?xml version="1.0"?>
<?xml-stylesheet href="chrome://global/skin/" type="text/css"?>

<window width="400" height="300"
    xmlns="http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul">

    <label value="ON TOP"/>

</window>

无效。

- 尝试'zlevel'：

test.xul：

<?xml version="1.0"?>
<?xml-stylesheet href="chrome://global/skin/" type="text/css"?>

<window width="400" height="300"
    onload="open('top.xul','GreenfoxChannelWindow','chrome');"
    xmlns="http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul">

    <label value="MAIN WINDOW"/>

</window>

top.xul：

<?xml version="1.0"?>
<?xml-stylesheet href="chrome://global/skin/" type="text/css"?>

<window width="400" height="300" zlevel="6"
    xmlns="http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul">

    <label value="ON TOP"/>

</window>

没有用。无法使用alwaysraised setted，或者向test.xul添加更高或更低的zlevel（使用top.xul zlevel =6）

didn't worked. Nither with alwaysraised setted, or adding a higher or lower zlevel to the test.xul (with top.xul zlevel="6")

推荐答案

找到：只需使用openDialog打开它，它将始终位于顶部。

Found: just open it using openDialog, and it will be always on top.

Ex：

<?xml version="1.0"?>
<?xml-stylesheet href="chrome://global/skin/" type="text/css"?>

<window width="400" height="300"
    onload="openDialog('top.xul','TopWindow','chrome');"
    xmlns="http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul">

    <label value="MAIN WINDOW"/>

</window>

top.xul：

<?xml version="1.0"?>
<?xml-stylesheet href="chrome://global/skin/" type="text/css"?>

<window width="400" height="300"
    xmlns="http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul">

    <label value="ON TOP" />

</window>
