Spectre Interactive Environment (SIE) in HI DPI display

SimbaG

I started the SIE from the Virtuoso ADE, virtuoso honor to the CDS_2DFORM_FONT_SCALING environment.

However SIE does not, which is expected as the environment name is CDS_xxx.

Looking up the SIE manual, not found some setting similar like that.

How to make SIE font better like Virtuoso CDS_2DFORM_FONT_SCALING? 

Spectre Version:

> spectre -W
sub-version 23.1.0.442.isr7

Edit:

Please see the external 3rd party link in the comments below and set QT_SCALE_FACTOR env.

    I would not expect SIE (Spectre Interactive Environment) to take any notice of CDS_2DFORM_FONT_SCALING because it does not use any old-style HI forms. The issue is that it is not inheriting the font/font size settings that you made in Virtuoso (presumably with hiSetFont("label" ?size 14) and hiSetFont("text" ?size 14) or similar).

    What I would suggest is that rather than changing the font sizes in Virtuoso, perhaps reset these to the default (bring up Options→Fonts in the CIW and then press the Defaults button and then OK), and instead set the QT_SCALE_FACTOR env var:

    setenv QT_SCALE_FACTOR 1.2

    This will also affect SIE. Icons scale, and 2D forms also scale properly - so you don't need to use the CDS_2DFORM_FONT_SCALING workaround to avoid overlapping fields on old-style 2D forms.

    Hi Andrew,

    Thank you for your reply. 

    I referred to this Qt official document.  https://doc.qt.io/qt-5/highdpi.html#high-dpi-support-in-qt

    It works well.

    Is there any method to change the QT_SCALE_FACTOR after starting virtuoso? (Avoiding restart virtuoso if change remote desktop)

    Best，

    No, there's nothing to do this. I don't think it would be possible.
