/**
* @brief File Chooser is a simple selector of file for opening, saving, and what you want ...
*
* As all other pop-up methode ( wost case we can have) the creating is simple , but event back is not all the time simple:
*
* Fist global static declaration and inclusion:
* [code style=c++]
* #include <ewol/widget/meta/Connection.h>
* [/code]
*
* The first step is to create the file chooser pop-up : (never in the constructor!!!)
* [code style=c++]
* ewol::widget::ConnectionShared tmpWidget = ewol::Widget::Connection::create();
* if (tmpWidget == nullptr) {
* APPL_ERROR("Can not open File chooser !!! ");
* return -1;
* }
* // register on the Validate event:
* tmpWidget->signalValidate.connect(sharedFromThis(), &****::onCallbackOpenFile);
* // no need of this event watching ...
* tmpWidget->signalCancel.connect(sharedFromThis(), &****::onCallbackClosePopUp);
* // set the title:
* tmpWidget->propertyLabelTitle.set("Open files ...");
* // Set the validate Label:
* tmpWidget->propertyLabelValidate.set("Open");
* // simply set a folder (by default this is the home folder)
* //tmpWidget->propertyPath.set("/home/me");
* // add the widget as windows pop-up ...
* ewol::widget::WindowsShared tmpWindows = getWindows();
* if (tmpWindows == nullptr) {
* APPL_ERROR("Can not get the current windows !!! ");
* return -1;
* }
* tmpWindows->popUpWidgetPush(tmpWidget);
* [/code]
*
* Now we just need to wait the the open event message.
*
* [code style=c++]
* void ****::onCallbackOpenFile(const std::string& _value) {
* APPL_INFO("Request open file : '" << _value << "'");
* }
* void ****::onCallbackClosePopUp() {
* APPL_INFO("The File chooser has been closed");
* }
* [/code]
* This is the best example of a Meta-widget.
