Re: [Apache - HSLF] - How to update a TextBox's text

[convoyer]

Hi
Thanks for the quick reply.

The first issue i solved with getting the text, as I have only textboxes and
rectangles.

The second issue:
I have already gone through the link you have added.
I can add a new text box by setting text to it.
But suppose if I have a textbox with the text "Default String" and I want to
update it to "Updated String", how it can be done??

Right now what I am doing is that I am retrieving the anchor of the textbox,
then deletes that textbox and then creates a new textbox with my text and
places it in the saved anchor. Is there any alternate way??

Also if you can excuse my knowledge in POI-HSLF, can u please solve the
following queries:

1) Can my textbox automatically adjust its size based on the size of the
text.

2) In the image part, can I put an image's URL just like

      int imgType = ppt.addPicture(new
File("http://www.thegreenhead.com/imgs/perpetual-motion-globe-2.jpg";),Picture.JPEG);

However this is not working for me :-(


Thank You
