說起傅雷,總不免說到他的嚴肅。其實他並不是一味板著臉的人。我閉上眼,最先浮現在眼前的,卻是個含笑的傅雷。他兩手捧著個煙斗,待要放到嘴里去抽,又拿出來,眼里是笑,嘴邊是笑,滿臉是笑。這也許因為我在他家客廳里、坐在他對面的時候,他听著鐘書說話,經常是這副笑容。傅雷只是不輕易笑;可是他笑的時候,好像在品嘗自己的笑,覺得津津有味。黄色电影免费 www.黄色电影.com 九 一幕鬧劇,躍然紙上。傅譯已達到相當高的藝術境界。這段對話中,個別語氣助詞是滬語,因為傅雷是上海人,上海小商販的吆喝聲使傅譯有生氣。倘能代之以北京小商販的吆喝聲就更精彩,因為普通話是以北京語音為標準的。誠然,傅雷的譯作還有不足之處,比如對話中個別句子過于書面化。我想,這與他倡導的要多“讀舊小說”不無關系,況且傅雷譯的巴爾扎克多在四十年代至五十年代成書,以當時文壇情況而論,傅譯的文筆可算是非常通俗、非常通暢、非常大眾化了。再者,巴爾扎克使用的詞匯量極大,個別詞又較冷僻,要貼切地譯出並非易事。傅雷自己也說︰“文字總難一勞永逸,完美無疵,當時自認為滿意者,事後仍會發見不妥。”翻譯家在藝術上精益求精的精神溢于言表。再想想傅雷1951年、1963年兩次重譯1944年初譯的《高老頭》一事,不能不使人對這位孜孜不倦、不斷探索的翻譯大師肅然起敬。黄色电影片 2019-07-29 16:02:29 +0800

Hi, guys! I have some trouble with scrollbar in the Listbox component - when I set the model to it and selecting several listitems, the scrollbar moves down to the last selected item, but I need to keep it on top. We've used simple zul as a view:

<zk>
<window xmlns="http: //www.zkoss.org/2005/zul" xmlns:xsi="http: //www.w3.org/2001/XMLSchema-instance"
        xsi:schemaLocation="http: //www.zkoss.org/2005/zul http: //www.zkoss.org/2005/zul/zul.xsd"
        use="com.otr.sufd.zkossforms.table.SetDocColumnsView"
        closable="true" border="normal" title="Customize columns" ctrlKeys="" height="400px" width="300px">
    <borderlayout width="100%" height="100%">
        <center>
            <listbox id="table" checkmark="true" vflex="true" fixedLayout="true" multiple="true" width="100%">
                <listhead>
                    <listheader align="left">Column title</listheader>
                </listhead>
            </listbox>
        </center>

        <south size="36" autoscroll="true">
            <toolbar align="end">
                <button label="OK" id="okButton" height="24px" width="75px" mold="os"/>
                <button label="Reset" id="resetButton" height="24px" width="75px"/>
                <button label="Cancel" id="cancelButton" height="24px" width="75px" mold="os"/>
            </toolbar>
        </south>
    </borderlayout>
</window>

</zk>

In SetDocColumnsView I filled Listbox by model and make some AfterCompose actions:

public void configureView(List<? extends HeaderElement> columns, Set<String> hiddenIds) {
    setSizable(true);

    final ListModelList tableModel = new ListModelList(columns);
    tableModel.setMultiple(true);
    table.setModel(tableModel);
    table.renderAll();
    for (int i = 0; i < columns.size(); i++) {
        final HeaderElement column = columns.get(i);
        if (column != null) {
            final Listitem listitem = table.getItemAtIndex(i);
            listitem.setLabel(column.getLabel());
            final String columnId = column.getId();
            listitem.setValue(columnId);
            listitem.setSelected(!hiddenIds.contains(columnId));
        }
    }
}
@Override
public void afterCompose() {
    table = (Listbox) getFellow("table");
    final Button okButton = (Button) getFellow("okButton");
    //adds some listeners to buttons
    addForward(Events.ON_OK, okButton, Events.ON_CLICK);
    addForward(Events.ON_CANCEL, cancelButton, Events.ON_CLICK);
    okButton.setFocus(true);
}

And then I show the dialog window by this code:

final SetDocColumnsView dialog = UIUtils.loadComponent(SetDocColumnsView.getUrl());
dialog.configureView(columnList, hiddenIds);
dialog.setPage(getPage());
dialog.doHighlighted();

I've tried to use some advice given in other threads, such as:

Clients.scrollIntoView(table.getItemAtIndex(0))

or call JS function inside my configureView method:

Clients.evalJavaScript("zk.Widget.$('" + dialog.table.getUuid() + "')._scrollToIndex(0);")

or keep all listitems what I need to select in a different Set and post to setSelectedItems method of Listbox, but everything is without success. Also, I've tried to debug a JS function _doScroll in Listbox.js but I don't figure out from where it has been called :(

I will be very appreciated if someone can help me with this problem.

Best regards, Roman

Yeah, I made simple zkfiddle example - http://zkfiddle.org/sample/1a44bo/1-scrollbar-in-listbox-moves-to-last-selected-item which reproduces the problem

Thanks for the zkfiddle example. Remove renderAll() can solve scrolling position issue. Listbox by default will render necessary Listitem for visible range, you don't need to call renderAll() which will enforce rendering all Listitems which is unnecessary for most cases. Please refer to http://zkfiddle.org/sample/1a44bo/2-scrollbar-in-listbox-moves-to-last-selected-item#source-2

Thank you for the response, hawk!

I tried to change the selection of items as you advised, but it doesn't solve my problem - when I select several items via ListModeList.setSelection, the scrollbar moves down to the last item. I made an example of that behavior in zkfiddle - http://zkfiddle.org/sample/1a44bo/1-scrollbar-in-listbox-moves-to-last-selected-item
