Touching and holding a link or form field is not visually reflected in the screen display

[rakunavi]

Hello all,

If you change your mind in the middle of clicking a link or button and have not yet released the mouse button, you can avoid the click operation by holding the button down and moving the mouse cursor outside the link rectangle or button field and releasing the button there. This is true not only for PDFs but also for web pages, and I think everyone is familiar with this. Now, when you perform this with touch operation, you will notice that the PDF-XChange Editor and Acrobat display differently on the screen.

In the video, the fingers are moving as indicated by the red broken line in the figure below.

Touch the inside of the link area or button field first, but do not release your finger immediately; instead, move your finger back and forth between the inside and outside of them, and finally release your finger outside of them. Since you do not release your finger inside, none of the actions set for the link area or button field will eventually work.

In PDF-XChange Editor, even if a finger touches the inside of a link area or button field, this is not reflected in any on-screen display; the only information is the locus of the touched area as displayed by the Windows operating system functions. In Acrobat, on the other hand, users get the same visual information as they would if they were operating the document with a mouse, such as inverted link areas and changing button field labels. The user can visually see that he or she is outside of the link or button by the link area being de-inverted or the button field's display content changing, allowing the user to release his or her finger with confidence.

I am not sure how much detail is specified in the ISO 32000-1:2008 standard, but I think there is room for improvement in the PDF-XChange Editor.

Hoping that the above information will be of some help to you.
Thank you so much for your continued support.

Best regards,
