Hello
I’m issue some troubles with libyui. I’m build up some ui, clear part of it using «deleteChildren()» method of one of my widgets and build another part of ui down from this widget. At first I have good working ui, but after above actions no any ui displayed. I’m check it on openSUSE 12.3 official and custom build libyui 3.0.10 with Qt and NCurses interface plugins - all the same. But with gtk interface plugin in openSUSE 12.3 all works fine. In some rare cases with same technique I got working interface in ncurses but not working Qt.
There is a sample code:
#include "YUI.h"
#include "YWidgetFactory.h"
#include "YDialog.h"
#include "YLayoutBox.h"
#include "YSpacing.h"
#include "YLabel.h"
#include "YPushButton.h"
#include "YEvent.h"
#include "YDialogSpy.h"
int main(int argc, char **argv)
{
/*****************************************************************************************/
auto mainDialog = YUI::widgetFactory()->createMainDialog();
auto mainVBox = YUI::widgetFactory()->createVBox(mainDialog);
auto mainLabel = YUI::widgetFactory()->createLabel(mainVBox, "Hello world!");
YUI::widgetFactory()->createVSpacing(mainVBox);
auto mainButton = YUI::widgetFactory()->createPushButton(mainVBox, "Close");
mainDialog->pollEvent();
YDialogSpy::showDialogSpy();
while (true) {
auto event = mainDialog->waitForEvent();
if (event)
if (event->eventType() == YEvent::CancelEvent || event->widget() == mainButton)
break;
}
mainDialog->deleteChildren();
/*****************************************************************************************/
mainVBox = YUI::widgetFactory()->createVBox(mainDialog);
mainLabel = YUI::widgetFactory()->createLabel(mainVBox, "Hello world #2!");
YUI::widgetFactory()->createVSpacing(mainVBox);
mainButton = YUI::widgetFactory()->createPushButton(mainVBox, "Close #2");
mainDialog->pollEvent();
YDialogSpy::showDialogSpy();
while (true) {
auto event = mainDialog->waitForEvent();
if (event)
if (event->eventType() == YEvent::CancelEvent || event->widget() == mainButton)
break;
}
mainDialog->destroy();
return 0;
}
