Description Rob Snelders 2011-10-20 12:15:20 UTC
I have added a scan-button to the unix-"select scanner"-dialog.
This still needs to be done for windows. Most of the work is done. What needs to be done:

- add a button to the windows-dialog (extensions/source/scanner/grid.*).
- change extensions/source/scanner/scanwin.cxx so it can handle scanning when the button is pressed.

You can look to the implementation in the unix-classes how it is done there. Please remember that the 2nd parameter of configureScannerAndScan isn't always initialized.

Is this regarding Libreoffice? If so what version are you using? Can you please provide us the steps to duplicate the issue?

We will need to know your OS Version .

A windows specific easy hack I guess; poke at this commit to see things work around there I guess.

Yes Michael that's correct.

I added a scan-button to the scan-settings-dialog in Linux. But I don't have windows so I can't implement it there. This bug describes that one there is also needed.

adding LibreOffice developer list as CC to unresolved EasyHacks for better visibility.

On Windows, we use dialogs provided by system TWAIN DSM. We can't add
a "Scan" button to the "Select source" dialog; but it's reasonable to
assume that user would select a scanner to scan, so let's proceed to
scan when user confirms selection in the dialog.
