Pashua Mac不允许我在输入框上对齐图像。我尝试了各种选择但无济于事

我最近开始玩Pashua，但似乎给我带来了一些麻烦。目前我正在将它用于shell脚本（Bash），并编辑了示例文件以接近我的愿望结果，但还没有到达那里。

我注意到一些事情。 Pashua有一个名为“Pashua.sh”的文件，我假设它试图找到应用程序以及bundle资源。现在我想知道，这是一个强制性文件，意思是：

我不能只在我自己的shell脚本中调用Pashua应用程序吗？即使我知道它永远不会改变的确切目的地。

我真的需要这个Pashua.sh文件吗？

我的最后一个问题是将图像重新定位到左上角。它只是不起作用，因为输入框位于顶部。我也放置了图像的绝对位置，但它不起作用。

#!/bin/bash -x

MYDIR="$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd )"

# Include pashua.sh to be able to use the 2 functions defined in that file
source "$MYDIR/pashua.sh"

# Define what the dialog should be like
# Take a look at Pashua's Readme file for more info on the syntax

conf="
# Set window title
*.title = App Store

# Add a text field
tf.type = password
tf.x = 100
tf.y = 200
tf.label = Example textfield
tf.width = 310

# Add a cancel button with default label
cb.type = cancelbutton
cb.tooltip = This is an element of type “cancelbutton”

db.type = defaultbutton
db.tooltip = This is an element of type “defaultbutton” (which is automatically added to each window, if not included in the configuration)
