java - Set a new JFileChooser FileFilter and reset previous ones -



java - Set a new JFileChooser FileFilter and reset previous ones -

i want file filter 2 options, 1 show files , other show specific extension.

the specific extension should 1 selected default.

i'm using same jfilechooser twice, first time show .fas files, , sec show .xls files.

right i'm using code, reasons not overwrite previous file extensions. many answers here on have similar code , same problem, if recycle jfilechooser.

first portion, works

filechooser.setfilefilter(new javax.swing.filechooser.filefilter() { @override public boolean accept(file file) { homecoming file.isdirectory() || file.getabsolutepath().endswith(".fas"); } @override public string getdescription() { homecoming "fasta"; } }); // more modern api, same result // filechooser.setfilefilter(new filenameextensionfilter("file fasta", "fas"));

second portion. used in sec "opening" of same jfilechooser. seems adds filter (the alternative select .fas files remains).

// delete name of selected file file currentdirectory = filechooser.getcurrentdirectory(); filechooser.setselectedfile(new file("")); filechooser.setcurrentdirectory(currentdirectory); // set new file filter filechooser.setfilefilter(new javax.swing.filechooser.filefilter() { @override public boolean accept(file file) { homecoming file.isdirectory() || file.getabsolutepath().endswith(".xls"); } @override public string getdescription() { homecoming "excel 97"; } }); // more modern api, same result // filechooser.setfilefilter(new filenameextensionfilter("excel 97", "xls"));

i guess name setfilefilter can misleading, because in reality set selected file filter (without replacing other filters).

if want recycle jfilechooser, simplest solution create phone call resetchoosablefilefilters() before setting new filters.

code first selection

filechooser.setfilefilter(new filenameextensionfilter("file fasta", "fas"));

code sec selection

// delete name of selected file, remain in same directory file currentdirectory = filechooser.getcurrentdirectory(); filechooser.setselectedfile(new file("")); filechooser.setcurrentdirectory(currentdirectory); // reset current file filters filechooser.resetchoosablefilefilters(); // set new file filter filechooser.setfilefilter(new filenameextensionfilter("excel 97", "xls")); // "all files" filter nowadays too, unless uncomment // filechooser.setacceptallfilefilterused(false);

java jfilechooser filefilter
