java - Has anyone figured out how to make a javafx tableview act like a jtable? -
i followed example 13-11 alternative solution of cell editing offical tableview tutorial, want tableview act jtable. means when cell gets focus, ready edited, , using arrow keys or enter key should instantly commit edit , move next cell.
this i've gone far:
first, added
table.getselectionmodel().setcellselectionenabled(true); then tried modify class editingcell:
class editingcell extends tablecell<person, string> { private textfield textfield; public editingcell() { } @override public void updateselected(boolean selected) { super.updateselected(selected); if (selected) { createtextfield(); settext(null); setgraphic(textfield); textfield.requestfocus(); textfield.selectall(); } else { string value = textfield.gettext(); if (value != null) { commitedit(value); } else { commitedit(null); } } } @override public void canceledit() { super.canceledit(); settext((string) getitem()); setgraphic(null); } @override public void updateitem(string item, boolean empty) { super.updateitem(item, empty); if (empty) { settext(null); setgraphic(null); } else { if (isediting()) { if (textfield != null) { textfield.settext(getstring()); } settext(null); setgraphic(textfield); } else { settext(getstring()); setgraphic(null); } } } private void createtextfield() { textfield = new textfield(getstring()); textfield.setminwidth(this.getwidth() - this.getgraphictextgap() * 2); textfield.focusedproperty().addlistener(new changelistener<boolean>() { @override public void changed(observablevalue<? extends boolean> arg0, boolean arg1, boolean arg2) { if (!arg2) { commitedit(textfield.gettext()); } } }); textfield.setonkeypressed(new eventhandler<keyevent>() { @override public void handle(keyevent t) { if ((t.getcode() == keycode.enter) || (t.getcode() == keycode.up) || (t.getcode() == keycode.down) || (t.getcode() == keycode.left) || (t.getcode() == keycode.right)) { t.consume(); string value = textfield.gettext(); if (value != null) { commitedit(value); } else { commitedit(null); } } else if (t.getcode() == keycode.escape) { canceledit(); } } }); } private string getstring() { return getitem() == null ? "" : getitem().tostring(); } } the tableview got mess - have click enter key twice end editing, , won't commit edit instead cancels it.
can point me in right direction?
sadly tutorial missing code fixes introduced later in textfieldtablecell class enter work (rt-34685 - use onaction instead of onkeypressed , rt-28132 - call requestfocus()).
here working example, it's reduced version of textfieldtablecell code uses node.fireevent() move next cell after commit (mimics keypressed event):
class editingcell extends tablecell<person, string> { private textfield textfield; public editingcell() { } @override public void startedit() { if (!iseditable() || !gettableview().iseditable() || !gettablecolumn().iseditable()) { return; } super.startedit(); if (isediting()) { if (textfield == null) { createtextfield(); } settext(null); setgraphic(textfield); textfield.selectall(); // requesting focus key input can go // textfield (see rt-28132) textfield.requestfocus(); } } @override public void canceledit() { super.canceledit(); settext((string) getitem()); setgraphic(null); } @override public void updateitem(string item, boolean empty) { super.updateitem(item, empty); if (empty) { settext(null); setgraphic(null); } else { if (isediting()) { if (textfield != null) { textfield.settext(getstring()); } settext(null); setgraphic(textfield); } else { settext(getstring()); setgraphic(null); } } } private void createtextfield() { textfield = new textfield(getstring()); textfield.setminwidth(this.getwidth() - this.getgraphictextgap() * 2); textfield.focusedproperty().addlistener(new changelistener<boolean>() { @override public void changed(observablevalue<? extends boolean> arg0, boolean arg1, boolean arg2) { if (!arg2) { commitedit(textfield.gettext()); } } }); // use onaction here rather onkeyreleased (with check // enter), otherwise encounter rt-34685 textfield.setonaction(t -> { commitedit(textfield.gettext()); t.consume(); }); textfield.setonkeyreleased(t -> { if (t.getcode() == keycode.escape) { canceledit(); t.consume(); } }); textfield.setonkeypressed(new eventhandler<keyevent>() { @override public void handle(keyevent t) { if ((t.getcode() == keycode.up) || (t.getcode() == keycode.down) || (t.getcode() == keycode.left) || (t.getcode() == keycode.right)) { // commit current text commitedit(textfield.gettext()); // let's move out simulating key press in cell keyevent event = new keyevent(t.getsource(), t.gettarget(), keyevent.key_pressed, "", "", t.getcode(), false, false, false, false); editingcell.this.fireevent(event); } } }); } private string getstring() { return getitem() == null ? "" : getitem().tostring(); } } hope helps!
