I added a Gtk.InfoBar to my ui and everthing looks OK. In Glade I can switch the Infobar to Revealed and vice versa.
On the valadoc.org Dokumentation set_revealedis listed in the allowed methods.
public void set_revealed (bool revealed)
Sets the GtkInfoBar:revealed property to revealed.
But when I'm building my Project I recive error: The name 'set_revealed' does not exist in the context of'Gtk.InfoBar'
What am I doing wrong?
Here's my code:
namespace Zeiterfassunggtk {
[GtkTemplate (ui = "/org/gnome/Zeiterfassunggtk/window.ui")]
public class Window : Gtk.ApplicationWindow {
[GtkChild]
Gtk.TreeView treeview1 = new Gtk.TreeView ();
[GtkChild]
Gtk.Button refreshbutton;

Gtk.MenuButton menubutton;
[GtkChild]
Gtk.Button menubuttonrefresh;

[GtkChild]
Gtk.InfoBar infobar1;
[GtkChild]
Gtk.Label infobar1label;
Gtk.TreeIter iter;
Gtk.ListStore liststore1 = new Gtk.ListStore (3, typeof (string), typeof (string), typeof (string));
private void setup_treeview (Gtk.TreeView treeview1) {
treeview1.set_model (liststore1);
treeview1.insert_column_with_attributes (-1, "Name", new Gtk.CellRendererText (), "text", 0, null);
treeview1.insert_column_with_attributes (-1, "Job", new Gtk.CellRendererText (), "text", 1, null);
treeview1.insert_column_with_attributes (-1, "Time", new Gtk.CellRendererText (), "text", 2, null);
liststore1.append (out iter);
liststore1.set (iter, 0, "Gerald", 1, "Job1", 2, "2018-01-01 18:23", -1);
}
void refresh () {
liststore1.append (out iter);
liststore1.set (iter, 0, "Gerald", 1, "Job1", 2, "2018-01-01 18:23", -1);
//infobar1.set_revealed (true);
}
void save () {
liststore1.append (out iter);
liststore1.set (iter, 0, "Gerald", 1, "Job2", 2, "2018-01-01 24:00", -1);
}
public Window (Gtk.Application app) {
Object (application: app);
this.maximize ();
this.setup_treeview (treeview1);
infobar1.set_revealed (false);
refreshbutton.clicked.connect (this.refresh);

}
}
You can find the full code at github.com
It seems you are importing an older Version of Gtk+. Your window.ui states <requires lib="gtk+" version="3.16"/>.
set_revealed is available from [ Version ( since = "3.22.29" ) ] though.
Seems you'll have to update.

I'm using this code to write the current time as a Gtk.Label in an app.
public bool update_time () {
var now = new GLib.DateTime.now_local ();
var settings = new GLib.Settings ("org.gnome.desktop.interface");
var time_format = Granite.DateTime.get_default_time_format (settings.get_enum ("clock-format") == 1, false);
time1_label = new Gtk.Label (now.format (time_format)) {
halign = Gtk.Align.CENTER,
valign = Gtk.Align.CENTER,
margin_top = 5
};
time1_label.get_style_context ().add_class (Granite.STYLE_CLASS_H3_LABEL);
time1_label.tooltip_text = time_format;
time1_label.xalign = 0;
return true;
}
The time shows correctly, but I want the label to update to the latest time when it changes. How can I do that?
Maybe use Timeout in some way, but I can't figure out how.
You'll have to create a Timeout, and in its callback change the text of time1_label. (Use Gdk.threads_add_timeout() to add the timeout callback in case any dependencies might be using deprecated GTK locking mechanisms.)
You can use the Timeout as in this example:
public class RefreshLabel : Gtk.Application {
private uint[] timeout_id;
private Gtk.Label label;
public RefreshLabel () {
Object (
application_id: "refreh.my.label",
flags: ApplicationFlags.FLAGS_NONE
);
}
protected override void activate () {
Gtk.ApplicationWindow window = new Gtk.ApplicationWindow (this);
window.set_default_size (100, 50);
window.window_position = Gtk.WindowPosition.CENTER;
window.set_border_width(10);
// create the timeout with your callback that update the label every 1 second
timeout_id += Timeout.add_seconds_full (GLib.Priority.DEFAULT, 1, update_time);
label = new Gtk.Label ("");
var now = new GLib.DateTime.now_local ();
label.set_markup ("<big>" + now.format ("%x %X") + "</big>");
Gtk.Box vbox = new Gtk.Box (Gtk.Orientation.VERTICAL, 0);
vbox.pack_start (label, false, false, 0);
window.add (vbox);
window.show_all ();
}
protected override void shutdown () {
// On close all instance of the timeout must be closed
foreach (var id in timeout_id)
GLib.Source.remove (id);
base.shutdown ();
}
public bool update_time () {
var now = new GLib.DateTime.now_local ();
label.set_markup ("<big>" + now.format ("%x %X") + "</big>");
return true;
}
public static int main (string[] args) {
RefreshLabel app = new RefreshLabel ();
return app.run (args);
}
}
I have a table with quantity and price columns that are editable and not disabled. The table is populated with ObservableList<Collection> . Collection object has a boolean attribute paid. What i am tring to achieve is whenever paid is true, make both price and quantity tablecells disabled and not editable.
This is what i have done so far:

The problem with my code is that as i scroll down the table and up again, cells which were previously enabled and editable change to disabled and not editable.
Before scroll After scroll:
The first problem is that you don't reset the state when a cell is reused from one which is paid to one which is not paid. This will happen, among other times, when you scroll. If a cell was previously used in a row that represented a "paid" item (so it is disabled, not editable, and has a red border), and is reused for an "unpaid" item, your updateItem() method will not change the editable or disabled state (or the style). So you should have something like:
if (item != null && item.isPaid()) {
setDisable(true);
setEditable(false);
this.setStyle("-fx-text-fill: grey;-fx-border-color: red");
} else {
setDisable(false);
setEditable(true);
setStyle("");
}
The second problem is that you have no control over the order in which the cell's state is updated. It seems that sometimes the row property is updated after the updateItem() method is called, so you end up with inconsistent state. You can safely use the cell's index to get the correct item from the table's data.
Also note that since both cell factories are identical, there is no need to replicate the code. This works for me:
#Override
public void start(Stage primaryStage) throws Exception {
TableView<Collection> tv = new TableView();
tv.setEditable(true);
TableColumn<Collection, Number> colQty = createQuantityColumn();
Callback<TableColumn<Collection, Number>, TableCell<Collection, Number>> cellFactory = new Callback<TableColumn<Collection, Number>, TableCell<Collection, Number>>() {
#Override
public TableCell<Collection, Number> call(TableColumn<Collection, Number> paramTableColumn) {
return new TextFieldTableCell<Collection, Number>() {
#Override
public void updateItem(Number s, boolean b) {
super.updateItem(s, b);
if (! isEmpty()) {
Collection item = getTableView().getItems().get(getIndex());
// Test for disable condition
if (item != null && item.isPaid()) {
setDisable(true);
setEditable(false);
this.setStyle("-fx-text-fill: grey;-fx-border-color: red");
} else {
setDisable(false);
setEditable(true);
setStyle("");
}
}
}
};
}
};
colQty.setCellFactory(cellFactory);
TableColumn<Collection, Number> colPrice = createPriceColumn();
colPrice.setCellFactory(cellFactory);
TableColumn<Collection, Number> colAmount = createAmountColumn();
TableColumn<Collection, String> colMno = createMNOColumn();
tv.getColumns().addAll(colMno, colQty, colPrice, colAmount);
tv.getItems().addAll(getCollection());
Scene scene = new Scene(new BorderPane(tv), 600, 400);
primaryStage.setScene(scene);
primaryStage.show();

I'm creating a report in "Jaspersoft iReport designer 5.6.0". What I'm trying to do is add a parameter (a static list that contains values such as: 6 months, 3 months ...). When the user chooses one of these options, I should be able in the Report query, to get the value that the user has chosen, so I can deliver the results upon that selection. I don't want to use jasper server.
Is this possible?
this is my query:
SELECT
DISTRICT."DKEY" AS DISTRICT_DKEY,
DISTRICT."PROVINCE_ID" AS DISTRICT_PROVINCE_ID,
DISTRICT."DISTRICT" AS DISTRICT_DISTRICT
DISTRICT."DURATION" AS DISTRICT_DURATION
FROM
"dbo"."DISTRICT" DISTRICT
where DISTRICT."DKEY" = $P{parameter1}
In iReport you can not create a static list (combobox) of your different month's you can only prompt for the insertion of parameter.
User will need to input manually 3,6 ecc.
<parameter name="parameter1" class="java.lang.Integer" isForPrompting="true">
<defaultValueExpression><![CDATA[3]]></defaultValueExpression>
</parameter>
iReport is not developed to be used by your client, but to be used by you when developing the report.
If you do not wish to use the jasperserver, you can develop your own application for user to select data ecc. Below you find an example of a java swing application, asking to select month and generating preview of the report (you need to fix the connection settings and provide correct path for the jrxml file):

No need for a custom renderer, just override the getColumnClass() method of the DefaultTableModel making the column with the boolean a Boolean object.

why you just don't do a "new JCheckBox()" instead of the second null??
I've been struggling to connect to the scroll_event of a TextView widget. I can connect a lambda to it, and then run my method, but I'd like to understand why directly connecting doesn't work. I've been using the code below
using Gtk;
public class TextFileViewer : Gtk.Window {
private TextView text_view;
public TextFileViewer () {
this.title = "Text File Viewer";
this.position = WindowPosition.CENTER;
set_default_size (400, 300);
this.text_view = new TextView ();
this.text_view.editable = true;
this.text_view.cursor_visible = true;
var scroll = new ScrolledWindow (null, null);

That code gives me the error:
gtkviewer.vala:20.46-20.60: error: Argument 1: Cannot convert from `TextFileViewer.on_scroll_event' to `Gtk.Widget.scroll_event'
scroll.scroll_event.connect (on_scroll_event);
vala is at version 0.12.0
Check the scroll-event signal arguments:
public virtual signal bool scroll_event (Gdk.EventScroll event);
private bool on_scroll_event (Gdk.EventScroll e) {
stderr.printf("We scrollin breds");
return true;
}
