I've been following a project based book which uses gtk and glade to build a UI. Went all fine until I got to using a gtk::Switch which the book uses like this:
let builder = gtk::Builder::from_string(include_str!("glade_config.glade"));
// ...
let is_dead_switch: gtk::Switch = builder
.get_object("is_dead_switch")
.unwrap();
Later on, to get the switch state it uses is_dead_switch.get_activate() but the method seems to no longer be a thing. I've looked into the documentation and found that gtk::Switch only has gtk::Switch::new listed as method. Anyone knows what's missing or what's wrong?

Since WSO2 5.0 supports WebSockets, I have written a simple app following by tutorials:
WebSocket Transport
Sending a Message from a WebSocket Client to an HTTP Endpoint
Here's my source view output from WSO2:

I was able to successfully test it with Nett client:
C:\work\servers\netty>java -Durl=ws://localhost:9091/websocket -DsubProtocol="synapse(contentType='application/xml')" -cp netty-example-4.1.4.Final.jar;lib/*;. io.netty.example.http.websocketx.client.WebSocketClient
WebSocket Client connected!
However if I try to test it from JavaScript code I am getting error like:
Do you know what is wrong in my code?
This issue occurs because SockJS internally trying to load the URL using XMLHttpRequest, but Chrome does not allow accessing cross origin content unless the protocol is one of the aforementioned protocols (In this case it is ws://). I have tried a similar scenario with Firefox and it works fine since it doesn't have this Chrome specific limitation.
In this scenario since WSO2 ESB exposes a WebSocket interface to invoke the HTTP Endpoint, you can use native HTML5 WebSocket implementation as follows.
var url = 'ws://localhost:9091/websocket';
var ws = new WebSocket(url);
ws.onopen = function() {
// todo
}
ws.onmessage = function(e) {
// todo
}
When working with CSV files and restarting a FAILED Job, a StepExecutionListner and associated beforeStep( ....) method can be used to position
the reader within the file. So the code could look something like:
public void beforeStep(StepExecution stepExecution) {
ExecutionContext executionContext = stepExecution.getExecutionContext();
if (executionContext.containsKey(getKey(LINES_READ_COUNT))) {
long lineCount = executionContext.getLong(getKey(LINES_READ_COUNT));
LineReader reader = getReader();
Object record = "";
while (reader.getPosition() < lineCount && record != null) {
record = readLine();
}
}
} // Or something similar
My question is how do you achieve the same thing when working with a StaxEventItemReader?
My batch_step_execution_context looks something like {"string":"StaxEventItemReader.read.count","int":6}. So in my case the
the first 5 XML fragment were successfully processed and upon restarting the Job I would like to start processing from XML fragment number 6 onwards.
Given the config below, how would I position the reader within the XML file?
<batch:job id="reportJob" restartable="true">
<batch:step id="step1">
<batch:tasklet>
<batch:chunk reader="xmlItemReader" writer="cvsFileItemWriter" processor="filterReportProcessor"

Test Result
Unfortunately it looks like the StaxEventItemReader is reading from the beginning of the file, rather than re-positioning itself based on the value of StaxEventItemReader.read.count which is set to 2 after the first test.
You don't need to configure anything, this is already the default behavior of the StaxEventItemReader. When it opens it repositions itself from the read count in the step execution context.
After spending a long time searching for an answer, I hope someone can help me with this problem. I'm trying to use gtkmm (version 3.14.0) and glade (version 3.18.3) on a Fedora 21 system to create a Gtk::TreeView/Gtk::ListStore with many small images. I can easily place stock icons in the list, but adding Gdk::Pixbuf objects seems to go wrong. No error or warning messages are shown, but the Gdk::Pixbuf image is not shown.
To show the problem, I've created a minimal working example (the code of the program and the glade file included at the end). Running this program should open a small window with the Gtk::TreeView with two "gtk-apply" icons. In the first column should be the icon added as Gdk::Pixbuf, in the second column should be the stock icon. However, when I run the program, the first column remains empty. There are no compile or run-time errors or warnings.
My final application will display a matrix of about 100 rows and about 35 columns of mostly tiny icons allowing a quick overview of activities done on the different days of a month. None of these icons will be stock icons.
Extra Information: Following the program execution using a debugger, I found that the Gtk::ListStore's first column wants data of type gtkmm__GdkPixbuf. The type of pb in the line row[cols.m_pb] = pb is GdkPixbuf. The type GdkPixbuf cannot be converted to gtkmm__GdkPixbuf automatically, causing the value to be set to 0 (NULL). Obviously this does not solve the problem, but might help to solve the problem.
Thanks for the help and best wishes for 2015,
Wim

The file mwe.cpp:

{

}
public:

Gtk::TreeModelColumn<Glib::ustring> m_stock;
};
static ModelColumns col;
} // End namespace ws
/**

*/
void ws::App::init(Glib::RefPtr<Gtk::Builder> builder)
{
builder->get_widget("mainwindow", m_mainwindow);
m_mainwindow->show();
Glib::RefPtr<Gtk::ListStore> store =
Glib::RefPtr<Gtk::ListStore>::cast_static(
builder->get_object("treatstore"));
Gtk::TreeModel::Row row = *store->append();
// The line below loads the stock icon as a pixbuf.
Glib::RefPtr<Gdk::Pixbuf> pb =
Gtk::IconTheme::get_default()->load_icon("gtk-apply", 16);
row[col.m_pb] = pb;
row[col.m_stock] = "gtk-apply";
}
int main (int argc, char *argv[])
{
Glib::RefPtr<ws::App> myapp = ws::App::create(argc, argv);
Glib::RefPtr<Gtk::Builder> builder = Gtk::Builder::create();
builder->add_from_file("mwe.glade");
myapp->init(builder);
return myapp->run();
}
After finding the problems in the types as shown in the Extra Information
section in the question, I decided to create the store by hand. The definition
of the GtkListStore was removed from the glade file. The ws::App::init()
method was changed to:
void ws::App::init(Glib::RefPtr<Gtk::Builder> builder)
{
builder->get_widget("mainwindow", m_mainwindow);
Gtk::TreeView *treeview = 0;
builder->get_widget("treattree", treeview);
Glib::RefPtr<Gtk::ListStore> store =
Gtk::ListStore::create(col);
treeview->set_model(store);
Gtk::TreeModel::Row row = *store->append();
// The line below loads the stock icon as a pixbuf.
Glib::RefPtr<Gdk::Pixbuf> pb =
Gtk::IconTheme::get_default()->load_icon("gtk-apply", 16);
row[col.m_pb] = pb;
row[col.m_stock] = "gtk-apply";
m_mainwindow->show();
}
Although this is not as flexible as hoped, it does fix the problem.

Please help me out.
Edit:
If you see, i have added QGraphicsWebView programatically. I am running this solution on my notebook, with 1366 x 768 resolution. If i want to use entire screen space, i have to give size to my QGraphicsWebView (line with comment added at the end) and to my QGraphicsView that lies in my MainWindow.ui. I want to remove this static part, and make it dynamic.
If you're using QLayout managers then all you should need to do is set the window state to full screen: QWidget::setWindowState. The layout managers should take care of the rest, most likely you'll need to set the spacing and use some QSpacers to get the elements exactly where you want them.
About the fullscreen issue: have you tried with QMainWindow::showFullScreen() ?
Reply to the edit:
I don't see any reason for those nested layouts, it is kinda messed up. Instead of having
-- mainLayout
|-- graphicsView
|-- buttonLayout <- why layout only one element??
|-- quitTutorialButton
try with this simpler layout
-- mainLayout
|-- graphicsView
|-- quitTutorialButton
Then, change the fixed size policy to MinimumExpanding instead.
Last advice: since looks like you layout your items by hand, never insert the outermost layout by hand. If you do so, the elements in it will never scale to the QMainWindow size.
Instead, right-click in an empty portion of the central widget, select Layout and then choose the type of layout you want to apply. This of course is needed only for the outmost layout: for the remaining, inner ones, you can add them by simple drag&drop as usual.
I'm mapping an Oracle 11g stored procedure as command in a NHibernate's .hbm.xml mapping file, like this:
<class name="Person" table="PERSONS">
<id name="Id" column="COD_PERSON" />
<property name="Name" column="NAME" />
<property name="AuditField1" column="AUDITFIELD1" />
<property name="AuditField2" column="AUDITFIELD2" />
<property name="AuditField3" column="AUDITFIELD3" />
<sql-insert>exec PKG_PERSONS.insert_sp ?,?</sql-insert>
</class>
This is the stored procedure:
create or replace package body PKG_PERSONS is
procedure insert_sp(pcod_person persons.cod_person%type,
pname persons.name%type) is
begin
insert into persons(cod_person, name) values(pcod_person, pname);
end;
From this mapping, I'm expecting 'Id' and 'Name' properties would be send as parameters, but for sure, this isn't happening; I'm getting this error from Oracle: ORA-01036: illegal variable name/number. NHibernate shows some logs in Console window and it seems like NH tries to map all properties, included AuditFields, to invoke the stored procedure.
Maybe is this the source's error?
Is this the expected behaviour?
Is it possible to specific what properties send as parameter with NH3/Oracle?
Thanks in advance.
Confirmed, NH tries to send as parameter every entity's properties mapped to <sql-insert>/<sql-update> stored procedures, but you could make exceptions with insert/update=false.
Another issue was the right sintaxis to execute Oracle11g's stored procedure, this is the mapping that works for me with NH3.3 and Oracle.DataAccess 4.112.2.0:
<class name="Person" table="PERSONS">
<id name="Id" column="COD_PERSON" />
<property name="Name" column="NAME" />
<property name="AuditField1" column="AUDITFIELD1" insert="false" update="false" />
<property name="AuditField2" column="AUDITFIELD2" insert="false" update="false" />
<property name="AuditField3" column="AUDITFIELD3" insert="false" update="false" />
<sql-insert check="none">begin PKG_PERSONS.insert_sp(:p0,:p1); end;</sql-insert>
</class>
I had to redefine the parameter's order, because Id property is send at last position:
create or replace package body PKG_PERSONS is
procedure insert_sp(pname persons.name%type,
pcod_person persons.cod_person%type
) is
begin
insert into persons(cod_person, name) values(pcod_person, pname);
end;
Maybe this will help somebody else,
Thanks.
