TextArea issues & questions

Hi list,

I have several issues/questions with TextArea:

1. When I copy and paste Excel data to TextArea, tab characters are
not displayed. For example, if I copy [data1][data2] in excel and
paste it onto TextArea, "data1data2" is displayed instead of
"data1<tab>data2" If I copy "data1data2" in TextArea and paste it onto
a text editor, it becomes "data1<tab>data2" so the tab character is
there, but just is not rendered. I also found that pressing Ctrl+Tab
enters four spaces instead of a tab character. Is it easy to
fix/customize this?

2. When text in TextArea is selected across multiple lines, font of
selected text looks different. If text is in English, it looks okay,
but when text is in Japanese, it looks funny. Is it possible to use
the same font for selected text?

3. Mouse drag in TextArea causes IndexOutOfBoundsException ->
https://issues.apache.org/jira/browse/PIVOT-693

4. InputText should support editable="false". I worked around with a
single line TextArea with editable="false", but the pain part is
TextArea doesn't scroll horizontally with mouse drag.

Greg,

I entered a bug:
https://issues.apache.org/jira/browse/PIVOT-697
Font looks different when text is selected across multiple lines in TextArea

I suspect it has something to do with how Java2D renders text with or
without antialias, but I don't have much experience in Java2D, so I
don't know.

It doesn't currently work for pasting text containing tabs, though - this should probably be entered as a bug.

Hm. I don't see anything obvious in the code that would cause what you are seeing. Maybe you can enter another JIRA ticket for this and attach a screen shot.

Greg,

For #2, I'm not talking about color change. Notice if you select part
of text within a single line, font of selected text looks the same,
while if you select text over multiple lines, font of the selected
text looks a little bit different. (Looks a bit fuzzy or maybe
anti-aliased.)

For #1, 4, I entered feature requests:

https://issues.apache.org/jira/browse/PIVOT-696
TextArea support for entering tab characters and tab stops

https://issues.apache.org/jira/browse/PIVOT-695
TextInput should support editable property

TextArea doesn't support the tab character because it doesn't support tab stops. Instead, Control-Tab key presses are converted to spaces. You can configure this via the tabWidth style. It doesn't currently work for pasting text containing tabs, though - this should probably be entered as a bug.

It should be the same font, but it is rendered in a different color. Is that what you mean?

Thanks.

I believe there is a feature request for this already, but if not please feel free to enter one.
