Tableviewer, click the first column to select all or none

Sometimes you need to click a column in the table to select all or none. You can set the text of the first column to null to implement this function. It is generally used on a check-style table or checkboxtableviewer.

Specific Code:

Tablecolumn columncheck = new tablecolumn (searchresults, SWT. None );

Columncheck. settext (""); // set the text ""

Columncheck. addselectionlistener (New selectionadapter (){

Public void widgetselected (selectionevent e ){

Setallcheckedstatus (! _ Boallselected); // You can select and cancel all options.

}

});

// Other columns

Tablecolumn columntitle = new tablecolumn (searchresults, SWT. None );

Columntitle. settext (messages. getstring ("playlistview. Title "));

Searchresults is of the table type, and tableviewer is encapsulated by table.

Searchresults = toolkit. createtable (searchresultclient, SWT.Check| SWT.V_scroll|
SWT.H_scroll| SWT.Full_selection);

Viewer = new tableviewer (searchresults );

Private void setallcheckedstatus (Boolean status ){

For (INT I = 0; I <searchresults. getitemcount (); I ++ ){

Searchresults. getitem (I). setchecked (Status );

}

_ Boallselected = status;

}
