Example 1 with DnDTransferItem

use of com.android.tools.idea.uibuilder.model.DnDTransferItem in project android by JetBrains.

the class NlPalettePanelTest method testCopy.

public void testCopy() throws Exception {
    myPanel.requestFocus();
    DataContext context = mock(DataContext.class);
    CopyProvider provider = (CopyProvider) myPanel.getData(PlatformDataKeys.COPY_PROVIDER.getName());
    assertThat(provider).isNotNull();
    assertThat(provider.isCopyVisible(context)).isTrue();
    assertThat(provider.isCopyEnabled(context)).isTrue();
    provider.performCopy(context);
    ArgumentCaptor<Transferable> captor = ArgumentCaptor.forClass(Transferable.class);
    verify(myCopyPasteManager).setContents(captor.capture());
    Transferable transferable = captor.getValue();
    assertThat(transferable).isNotNull();
    assertThat(transferable.isDataFlavorSupported(ItemTransferable.DESIGNER_FLAVOR)).isTrue();
    Object item = transferable.getTransferData(ItemTransferable.DESIGNER_FLAVOR);
    assertThat(item).isInstanceOf(DnDTransferItem.class);
    DnDTransferItem dndItem = (DnDTransferItem) item;
    assertThat(dndItem.getComponents().size()).isEqualTo(1);
    DnDTransferComponent component = dndItem.getComponents().get(0);
    assertThat(component.getRepresentation()).startsWith(("<TextView"));
