The usage of function setItemMetrics() in Table.js [message #512829]

Hello all experts:

I found a javascript function in Table.js which is named as setItemMetrics but could not find any reference to it.

I am now facing a problem probably caused by the usage of this method and hope to get some suggestion...

I have two images with different sizes(100x16 & 16x16) in cells of two different columns.when the table is shown, the image area of the small one is set as wide as the bigger one which means the AREA(but not the image itself) of the 16x16 sized image is enlarged to 100x16. I tracked this problem down and found that the only entry to image width modification was the setItemMetircs function but now am blocked cos I just can't find out by which class this function is called.

Could you please lend me a hand?

As you might have known, my RAP version is 1.2:)

Thx and Best Regards!

Tingel Christian.

Hi Tingel,

the Table.js#setItemMetrics is called from the server side - see
TableLCAUtil#writeItemMetrics(Table).

HTH,
Ivan

C U again, Ivan, and thanks a lot:)

I followed your direction and finally found the root cause of the problem who lies in the following code:

Table#getItemImageSize():
final Point getItemImageSize() {
return itemImageSize == null ? new Point( 0, 0 ) : itemImageSize;
}

This means that all images in a table can and can only occupy an equally-sized image area.

Don't you think that allowing all images in a table have their own image area would be better?

Thanks and Best Regards!

Hi Tingel,

does SWT support different image sizes? If yes, please file an
enhancement request.

Best,
Ivan

Hi Ivan:

Unfortunately, SWT does not support this function either, but honestly I don't think this is a proper specification cos you know it's really a big constrain for developers who are always facing this and that kinds of requirement and you can hardly require them all not to use images with different size in different columns, right?

So if you don't mind, I wish the RAP/RCP team could have a little bit consideration about the specification -- RAP/RCP do support different sized images in tableviewer, but to use it or not, it's up to the user.

Any way, I am a big fan of RCP/RAP who wishes them getting better and better and I hope you wouldn't regard me as a trouble maker~~~ Smile

Thanks a lot and Best Regards!

Christian,

this issue has been discussed before. The least common denominator here
is Windows [1] (see there for a workaround).
I am sorry to say, but we are currently not considering to implement
this for two reasons. The compatibility to SWT and the fact that it is a
considerable amount of work to implement.

Regards,
Rüdiger
