In Adobe Reader after zoom in, it is possible to move the site e.g. for searching some detail: press and hold Space key and then with left mouse button you can move the site.

Is it the same possible with PDFium?

Sorry Marek, I'm not sure what you mean by that. Shift doesn't seem to do anything for me in Reader other than select text.

I wrote about Space key, not the Shift key.

It is the same as with pictuer in TImageEnView:
- zoom in the image so it is bigger as the window
- press the left mouse button
- the cursor changes to the hand
- hold the mouse button and move the mouse
- the picture moves in the window

Hi Marek

Can you tell me a little more about your need for this feature?

miScroll and miZoom can already be used together in ImageEn (as well as miScroll and miDblClickZoom) so I don't understand the requirement for the space bar modification.

Hi Nigel,

I attached small video how it work in Adobe:
- First, the page is enlarged so that it no longer fits in Window
- Now press and hold the space bar until the mouse cursor changes to hand
- Press and hold the left mouse button and move the mouse
- The page moves in window

Thanks for the video, Marek.

It seems like it is only useful if you are using it in combination with something else, e.g. MouseInteractGeneral is miSelect (can select text, etc), but when the space bar is down it becomes miScroll. Is that correct?

Please email me for the latest beta that supports this.

Note: you need to add miSpaceBarToScroll to MouseInteractGeneral, e.g.

// Allow rectangular selections, plus double-click to zoom, and scrolling when the Space key is down
ImageEnView1.MouseInteractGeneral := [ miSelect, miDblClickZoom, miSpaceBarToScroll ];
