PageDisplay

rbuser

Hello,

I'm not using the standard PreviewForm, but a own PreviewForm. Now I
want to implement the new features of PageDisplay. So I'm setting some
buttons on the form and call for example :

FPreview.Viewer.PageDisplay := pdContinuous;

But nothing happens. If I'm checking with debugger the PageDisplay
property is still set to pdSingle.

Is there something else I have to do that it works? Is there somewhere
an example how I can implement these features?

Best wishes
Bernhard

Hi Bernhard,

If you are using a preview, you will want to set the PageDisplay
property of the Report.PreviewFormSettings instead of the viewer directly.

Hi Nico,

I've tried this, too. In this case I see with debugger that
Report.PreviewFormSettings.PageDisplay is indeed pdContinuous. But on
the screen nothing happens.

Is there something else I have to do, like a refresh or something else?

Best wishes
Bernhard

Hi Bernhard,

There is nothing else you should have to do. If you try this with the
built-in previewer and a simple report, do you still get the same behavior?

The only other item I can think of is that perhaps you are loading
templates in which case, the property needs to be set after the template
is loaded.

Hello,

I am also trying to implement the PageDisplay property in my custom made
Print preview form.

Setting PageDisplay doesn't do anything in my case, either.

I am indeed loading templates, too.

I have tried setting the PageDisplay property right after the template
has been loaded. It DOES work there.

But this is no good. Once I have the template loaded, I need the end
user to be able to change the PageDisplay property - just as it is in
the built in Preview form, where it works just fine.

Obviously I need to call something else after setting PageDisplay.

What is it?

Thanks.

Hi Dimitar,

If you take a look at the TppPreview.PerformPreviewAction routine, you
will see exactly what is executed when a button is pressed in the
default preview.

I suggest you trace through this code with the default preview and your
custom preview to find the differences. My initial guess is that the
ScrollableScreenDevice is nil meaning that the SinglePageOnly property
is set to True.
