Implemented in TD 7.3

[Uwe van der Horst]

It has been implemented, but the implementation is very rudimentary.In Attribute Inspector you find the attributes "Vertical Anchor" and "Horizontal Anchor". You can set these attributes to "Top/Bottom/Both/None". This leads to a major limitation. There is no way to resize the elements in proportion to the form window. Only one "level" (= items next to each other or items below the other) can be resized horizontally or vertically. I have requested to add a function to provide the proportional resizing percentage of the elements. I also requested a new flag for grid columns to be able to resize them also in proportion to its parent.

[Uwe van der Horst]

TD-25538 - Request to add new attributes to specify a percentage for each element for resizing both horizontally and vertically - is scheduled to implement in TD 7.5
Zooming was part of the DevDay presentations and is scheduled for TD 7.4. Very good feature.

[Dave Rabelink]

TD-25538 is implemented in TD 7.4

[Uwe van der Horst]

It is listed in the release notes, but I don't see this

[Igor Ivanovic]

Me neither...

A bit strange zooming, I can set up the zoom to 150 or 400 but not to less than 100

And it doesn't work on dialogs and dockable dialogs

That is correct. TD 7.4 uses simply the font size as basis for the zoom feature. So the zoom works between 100% and 400% without discrete little steps < 25.

If you want to use this feature, you should be aware of conflicts if your application contains elements that are manually sized, such as Windows Defaults of TD, in the Attribute Inspector, SalFontSet() or elsewhere.

It works, but contrary to the documentation SalZoomWindow( hWndForm, nZoom ) is an application setting. It is not possible to have different zoom factors for different top level windows. The first parameter is actually without function.

I took part in the beta test. At first it was possible to set a different zoom factor for dialogs, but there were some ugly effects. Opentext then opted for a pragmatic solution
In the private betatest discussion I got this information from Opentext:

Now SalZoomWindow ignores window specified as argument and zoom all TD windows. This zoom functionality is done by changing logical resolution of display (emulating display scaling) so that it's so hard to zoom only specific form window. I haven't changed SalZoomWIndow prototype because we might support it in the future.

Nils, you are totally right, in TD 7.40 it does not work. Gupta changed the behaviour during the beta test. I opened a ticket.

OpenText/Gupta should have special release, say TD 7.5 only for Zoom and Anchoring for Windows and WPF and take care everything in this release.

Thanks!
