|
|
* 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/FileChooser.hpp>
|
|
* [/code]
|
|
*
|
|
* The first step is to create the file chooser pop-up : (never in the ructor!!!)
|
|
* [code style=c++]
|
|
* ewol::widget::FileChooser tmpWidget = ewol::widget::FileChooser::create();
|
|
* if (tmpWidget == null) {
|
|
* 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::Windows tmpWindows = getWindows();
|
|
* if (tmpWindows == null) {
|
|
* 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( 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.
