Description tmacalp 2014-01-14 17:10:50 UTC
In Calc, if you select cells that contain different font types, it causes issues with the font selector drop-down.  From what I can tell, either using the scroll bar, scrolling down with the mouse wheel, using the arrow keys, or even keying in another font will cause the font selector to revert back to displaying None.  This causes the selection to go back up to the top of the list.

Steps to reproduce
* Create a new spreadsheet
* Change the font in B1 to some font other than the default
* Select A1:B1
* Click on the dropdown arrow in the font selector (pulls up list of fonts)
* Scroll down using mousewheel, pressing down arrow, typing, etc...

We should be able to select and apply any font, without having to race the dialog resetting.

Font selection is "reset" back to blank and keeps resetting to blank each time you try to select any other font.  If you're quick, you can click on a font and that font is applied to the selection.

This behavior of setting the font selector to blank is what happens when you first make your selection that includes multiple font types.  That's the intended behavior, since it can't show more than one font.  But after that point, it should never have to reset back to blank again.

Versions tested
I tested a number of versions and it seems that this bug was introduced with the 4.1.x line and also affects the prerelease.  4.0.x versions are unaffected.

LibreOffice under 32bit Fedora 17
LibreOffice under 32bit Fedora 17
LibreOffice under 64bit RHEL6
LibreOffice under 32bit Windows7

LibreOffice under 32bit Fedora 17
OpenOffice 3.2.1 under 64bit RHEL6
Comment 1 Cor Nouws 2014-01-14 19:52:51 UTC

thanks for the issue. I see the same in As long as the mouse pointer is over the scroll bar, I can go down. As soon as the mouse pointer is over the list, the focus jumps back.

(There was a similar issue some time ago for the list behaviour, but without more fonts in the selection involved - cannot find it now)

See it in 4.1.0rc1 (do not have the alpha versions here) is OK in

That's right. It's due to invalidation of SID_ATTR_CHAR_FONT during live preview. Called from:


When the selection consist of multiple fonts, it leads to the following code in SvxFontNameToolBoxControl::StateChanged:

if ( SfxItemState::DEFAULT == eState )
    pBox->SetText( "" );
