Wt

Hello,

I have trouble getting CSS to work using the information at https://www.webtoolkit.eu/widgets/layout/css. Here is my program:

#include <Wt/WApplication.h>

#include <Wt/WContainerWidget.h>

#include <Wt/WText.h>

#include <Wt/WTable.h>

class App : public Wt::WApplication

{

public:

App(const Wt::WEnvironment& env);

private:

Wt::WTable *m_table;

};

App::App(const Wt::WEnvironment& env)

: Wt::WApplication(env)

{

setTitle("App");

Wt::WApplication::instance()->useStyleSheet("CSSexample.css");

auto container = root()->addWidget(std::make_uniqueWt::WContainerWidget()); //nothing is visible on the page if container is not added to root.

container->setStyleClass("CSS-example");

m_table = root()->addWidget(std::make_uniqueWt::WTable());

m_table->setStyleClass("table table-bordered");

m_table->setHeaderCount(1);

m_table~~elementAt(0, 0)>addWidget(std::make_uniqueWt::WText(""));

m_tableelementAt(0, 1)>addWidget(std::make_uniqueWt::WText("Density)"));

m_tableelementAt(0, 2)>addWidget(std::make_uniqueWt::WText("Weight"));

m_tableelementAt(1, 0)>addWidget(std::make_uniqueWt::WText("A_090917"));

m_tableelementAt(1, 1)>addWidget(std::make_uniqueWt::WText("853"));

m_tableelementAt(1, 2)>addWidget(std::make_uniqueWt::WText("832"));

m_tableelementAt(2, 0)>addWidget(std::make_uniqueWt::WText("B_110817"));

m_tableelementAt(2, 1)>addWidget(std::make_uniqueWt::WText("723"));

m_tableelementAt(2, 2)~~>addWidget(std::make_uniqueWt::WText("711"));

}

int main(int argc, char **argv)

{

return Wt::WRun(argc, argv, [](const Wt::WEnvironment& env) {

return std::make_unique(env);

});

}

And here the CSS file (copied from the CSS example):

.CSS-example table {

width: 0%;

margin-top: 20px;

margin-bottom: 20px;

}

.CSS-example .table-bordered {

border: 1px solid #DDD;

border-left: 0;

border-radius: 4px;

}

.CSS-example .table-condensed th,

.CSS-example .table-condensed td {

padding: 4px 5px;

}

.CSS-example .code {

font-family: andale mono;

color: #570;

font-size: 97%;

}

.CSS-example .info {

background-color: #D9EDF7;

}

I start the application with these arguments:

---docroot . ---approot . ---http-address 0.0.0.0 ---http-port 9090

I have spent 2 days trying to get this to work with all kinds of variations to the code and to argument starting the program. I suspect the program does not find the CSS file. auto x = appRoot(); returns null, ./ or the path that I explicitly defined in ---approot (with a trailing slash, is this expected on windows?) During compilation i have #defined WIN32. I keep the CSS file in the same folder as the executable.

I installed Wt-4.0.0-msvs2017-Windows-x64-SDK.exe on Windows 10.

What I need to do is to present some data in a table. Without formatting it is difficult to read.
