Examples with IntegerBinding javafx.beans.binding.IntegerBinding used on opensource projects

Example 1 with IntegerBinding

use of javafx.beans.binding.IntegerBinding in project POL-POM-5 by PlayOnLinux.

the class MainWindow method createInstallationsTab.

private Tab createInstallationsTab(InstallationsFeaturePanel installationsFeaturePanel) {
    final Tab installationsTab = new Tab(tr("Installations"), installationsFeaturePanel);
    installationsTab.setClosable(false);
    final ConcatenatedList<InstallationDTO> installations = ConcatenatedList.create(new MappedList<>(installationsFeaturePanel.getInstallationCategories(), InstallationCategoryDTO::getInstallations));
    // a binding containing the number of currently active installations
    final IntegerBinding openInstallations = Bindings.createIntegerBinding(installations::size, installations);
    final TabIndicator indicator = new TabIndicator();
    indicator.textProperty().bind(StringBindings.map(openInstallations, numberOfInstallations -> {
        if (numberOfInstallations.intValue() < 10) {
            return String.valueOf(numberOfInstallations);
        } else {
            return "+";
        }
    }));
    // only show the tab indicator if at least one active installation exists
    installationsTab.graphicProperty().bind(Bindings.when(Bindings.notEqual(openInstallations, 0)).then(indicator).otherwise(new SimpleObjectProperty<>()));
    return installationsTab;
}

Example 2 with IntegerBinding

use of javafx.beans.binding.IntegerBinding in project arquivoProject by fader-azevedo.

the class PdfViewerController method bindPaginationToCurrentFile.

private void bindPaginationToCurrentFile() {
    currentFile.addListener(new ChangeListener<PDFFile>() {

        @Override
        public void changed(ObservableValue<? extends PDFFile> observable, PDFFile oldFile, PDFFile newFile) {
            if (newFile != null) {
                pagination.setCurrentPageIndex(0);
            }
        }
    });
    pagination.pageCountProperty().bind(new IntegerBinding() {

        {
            super.bind(currentFile);
        }

        @Override
        protected int computeValue() {
            return currentFile.get() == null ? 0 : currentFile.get().getNumPages();
        }
    });
    pagination.disableProperty().bind(Bindings.isNull(currentFile));
}
