Example 1 with FileEditorState

use of com.intellij.openapi.fileEditor.FileEditorState in project intellij-community by JetBrains.

the class UndoRedo method restore.

private boolean restore(EditorAndState pair, boolean onlyIfDiffers) {
    if (myEditor == null || // editor can be invalid if underlying file is deleted during undo (e.g. after undoing scratch file creation)
    !myEditor.isValid() || pair == null || pair.getEditor() == null) {
        return false;
    }
    // 5. undo -> position is not affected, because instance created in step 4 is not the same!!!
    if (!myEditor.getClass().equals(pair.getEditor().getClass())) {
        return false;
    }
    // If current editor state isn't equals to remembered state then
    // we have to try to restore previous state. But sometime it's
    // not possible to restore it. For example, it's not possible to
    // restore scroll proportion if editor doesn not have scrolling any more.
    FileEditorState currentState = myEditor.getState(FileEditorStateLevel.UNDO);
    if (onlyIfDiffers && currentState.equals(pair.getState())) {
        return false;
    }
    myEditor.setState(pair.getState());
    return true;
}
