QTextImageFormat HTML not write <img width= height>

[patrik08]

I have build a small html editor (to append on a CMS - CRM ) that load automatic image remote or local in to local Cache
and i enable drag in image or text/html text/plain and to edit all text attribute also table ...... but now i have problem on
image attribute width="xxx" height="xxx" ..

On Edit::RContext( const QPoint & pos ) (Contex menu) i grab QTextImageFormat from image i open Image_mod_Setting() on a
dialog and i edit image large height and save image and i send back QTextImageFormat and my problem ....

QTextImageFormat not write the new width="xxx" height="xxx" !!

On QTextTableFormat runn all ok and set all attribute correct padding bgcolor spacing ecc... and QTextImageFormat no! why?

What does Edit_Image::self( this )->GetFormat() do?

[patrik08]

What does Edit_Image::self( this )->GetFormat() do?

is return the old QTextImageFormat .... + new height() width() name stay same....

here is dialog ... on qtexttable format its work wonderfull on same way ....
i put QTextTableFormat to dialog modify attribute and get return ... in one way
no signal or emit ....

Where do you actually use "nowimage" as the format for your image?

[patrik08]

Where do you actually use "nowimage" as the format for your image?

QTextImageFormat nowimage;

Contain all image data can extract and reinsert ....
1 - NAME *** path
2 - name from resource
3 - can save height
4 -weight

+ info from
doc->addResource( QTextDocument::ImageResource, QUrl(filename), QPixmap(QString("%1%_%2").arg(registername).arg(im posi)) );

on load html i RegExp

QRegExp expression( "src=[\"\'](.*)[\"\']", Qt::CaseInsensitive );
expression.setMinimal(true);

all image list and download remote image to cache and local image go to cache ....
why? i prepare all image to same dir to zip & upload after on remote cms dir ...
and i must only replace cache dir with the remote dir path.....
to edit or reedit i get the remote zip to cache image....

How You chance wieth height attribute on img tag? all img to QRegExp

Why #include "table_setting.h" run so clean and chance all table attribute? + cell row ecc...

QTextTableFormat & QTextImageFormat have different Target .. to usage?

[jacek]

Where do you change the format of an image that is already in the document? Because it seems that you never use the information stored in "nowimage".

Where do you change the format of an image that is already in the document? "nowimage".

Yes i reformat .... image inside qtextbrowser .... & not open other apps photoshop or so... the image must stay on html size ... and not waist time to other photoshop or gimp action...

table i reformat so ... is run OK super....
