The first step is to configure the repositories. Create the following file /etc/yum.repos.d/10gen.repo with the following contents:
For 32-bit systems:
[10gen] name=10gen Repository baseurl=http://downloads-distro.mongodb.org/repo/redhat/os/i686 gpgcheck=0 enabled=1 For 64-bit systems:
[10gen] name=10gen Repository baseurl=http://downloads-distro.mongodb.org/repo/redhat/os/x86_64 gpgcheck=0 enabled=1 Install Mongo
yum install mongo-10gen mongo-10gen-server Configure MongoDB You can configure Mongo by editing the following file:
/etc/mongod.conf Set Mongo to autostart on system boot:
chkconfig mongod on Start Mongo
service mongod start Stop Mongo
In this entry I’m going to create a simple form. This form will show you how to use controls and events in a very simple way.
A couple things you have to notice before we start:
I’m going to inherit from WContainerWidget. As you now know, I could have inherited from WApplication too. Most controls like, WLabel, WLineEdit and WPushButton include a “parent” parameter in their constructors. But you can also create them and add them later to any WContainerWidget.
