Text selection with mouse

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   hello!

I've looked through the whole forum - maybe I've missed it, but:

how can I display a PDF and the user is able to select text with pressed mouse button
like allmost any reader (acrobat, pdf exchange viewer, ...) can?

I stuck to find the right function of the lib.
renderPage delivers only a bitmap with rendered text without any information where the text is located; ExtractPageTextBlocks delivers only the text without any "visual" context.

Do you have any hint?
That would be really great!
Thank you!

	Hi Gini! You can get textcontent from a determined section of a page by doing the exraction with position data and then selecting the pixel-coordinates you want. The combination with mouse-activities isn't a built-in-functionality. The comparison with acrobat and co isn't fair - on one side there's an acrobat-installation with more then 100 mb and on the other side there's the small quickpdf-lib ;-) The solution should be anywhere by drawing onto canvas and then dealing with mousemove... mouseclick... Cheers, Ingo
	Cheers, Ingo

	ginidat, Debenu Quick PDF Library doesn't not have any functions designed to interact with the GUI / Mouse. It is possible to create such an editor with QPL but it does take a little bit of work. Andrew.

	Hello and Thank you for your replies! My mistake: I did not really believe that there is a build in function! And: I don't want to compare with full featured pdf reader/viewer! I ambition was to get a hint for a "how to". Your approach, Ingo is the thing! Thank you very much! Cheers, Gini

	ginidat, The two functions you have mentioned would provide the basics. What language are you using ? Here are some links to give you some low levels hints on how to do what you need. http://stackoverflow.com/questions/16851654/draggable-selection-rectangle You should find something relevant here in these search results. http://stackoverflow.com/search?q=rectangle+mouse+draw Andrew.
