可可苹果：确定进度指标 [英] cocoa-applescript: Determinate progress indicator

问题描述

我正在制作一个使用Cocoa-Applescript的应用程序，该应用程序通过ping x.y.z. [1-255]来标识正在运行的本地IP地址，并将运行中的IP追加到文本文件中。我已经有了用于选择x，y和z的GUI，并且已经制作了脚本来ping每个地址：

I am making an application using Cocoa-Applescript which identifies local IP addresses which are up and running, by pinging x.y.z.[1-255] and appends running IPs to a text file. I already have a GUI for choosing x, y and z and have already made the script to ping each address:

repeat 255 times
         try
            do shell script "ping -o -t 1 -c 1 " & ipstamp & num4
            do shell script "echo " & ipstamp & num4 & " >>/Users/DJ/Desktop/GoodIPs.txt"
        end try
        set num4 to (num4 + 1)
    end repeat

其中 ipstamp 是xyz和 num4 是[1-255]。但是现在我想要一个进度指示器，以显示进度。我知道如何获得一个不确定的指标，该指标可以简单地开始和停止：

Where ipstamp is x.y.z and num4 is the [1-255]. But now I want a progress indicator to show where it is up to in the process. I know how to get an indeterminate indicator which simply starts and stops:

ProgressBar's startAnimation_(ProgressBar)
## code to ping IP address
ProgressBar's stopAnimation_(ProgressBar)

但这只是不确定的，我可以找不到有关在Cocoa-Applescript中设置确定的信息，设置其最大步长和设置其当前步长的信息-就像在常规Applescript中一样：

But that is only indeterminate and I can not find any info on setting determinate ones in Cocoa-Applescript, setting their maximum steps and setting their current step - much like in regular Applescript's:

set progress total steps to x
set progress completed steps to y

除了它在GUI中，所以我需要使用NSProgressIndicators来完成它。综上所述，如何制作确定进度条，如何设置其总步长以及如何更新其当前步长？

Except it is in the GUI, and so i need to use NSProgressIndicators to do it. So summed up, how do you make a determinate progress bar, how do you set its total steps and how do you update its current step?

可以对其进行更改以在菜单构建器的属性检查器中进行确定，包括最大，最小和当前步骤。但是，我确实需要能够从脚本中更改最大步数和当前步数，因此这些步数仍然适用。

It can be changed to determinate in the menu builder's Attribute Inspector, as can max, min and current steps. However I do need to be able to change the maximum and current steps from within the script, so those still apply.

推荐答案

好您可以制作一个确定进度的指标，但是问题是您必须重复使用

Well you can make a Determinate progress indercator but the problem is you have to repeat telling it to go to a certain lenght by using the

setDoubleValue_()

消息，但是无论如何，这里有一个简单的脚本告诉它去100

message, but anyway here is a simple script to tell it to go to go up to 100

property MyProgressBar : missing value -- Progress Bar IB Outlet

on applicationWillFinishLaunching_(aNotification)
    set c to 0
    repeat 100 times
        set c to c + 1
        delay 0.2
        tell MyProgressBar to setDoubleValue_(c) -- Tells Progress bar the % to go to
        if c > 99 then
            exit repeat -- If current repeat is 100 or more then cancels adding more
        end if
    end repeat
end applicationWillFinishLaunching_
