FileFormat plugin issue

[Guest]

Hi ,

I am facing a issue in fileformat plugin in PhotoShop CS6...  i am doing some fuctionalaties on "formatSelectorFilterFile" signal. But in MAC, Photoshop is sending this signal twice. first, when user do File -> open(in PhotoShop CS6) and just select any photoshop file and second when user click on open button. first time PhotoShop is sending signal as MAC tries to open file to show preview in  open dialog box. I am not finding any way so that  I can differntiate between these two condition. actully i don't want first one.

Thanks in advance

I guess the first one was put there for a preview/thumbnail generation (Adobe folks probably know better though).

In any case, this selector simply asks whether you plugin can handle the filie format and therefore it has to be lightweight, since youy don't really want to introduce delays as the user goes over the file list. If properly implemented as only a test, you shouldn't really care about this selector being invoked multiple times.
