Question

我正在利用WT MVP和UiBinder,与一家DockLayoutPanel一道制作一个信片。我想,北部和南部的码头是固定的,有 but子和连接。我想对中部和东部两处不同地区有积极的看法。由于这些动态领域彼此独立,我正在为每个有活力的展示区、中心、东方和东西方建立了不同的活动管理和活动管理。

当申请装满时,我如何能够独立地启动这3个不同的展示区? 我如何能够在一个展示区从一个活动转向另一个活动,而不影响其他领域?

当我利用地方主计长前往一个地区从一个地方向另一个地方转移时,另一个地区的活动就会停止。

5月份,请帮助,或许是天!

以下是我的一些法典:

AppViewImpl.ui.xml

<g:DockLayoutPanel styleName="{style.dockPaneliii" unit="PX" width="975px" height="100%">

    <!-- DOCK PANEL EAST -->
    <g:east size="220">
        <g:LayoutPanel styleName="{style.eastPaneliii">
            <g:layer left="0px" width="220px" top="0px" height="105px">
                <g:SimpleLayoutPanel ui:field="topRightPanel"/>
            </g:layer>

            <g:layer left="0px" width="220px" top="110px" height="340px">
                    <g:InlineLabel styleName="{style.labeliii" text="ANOTHER DISPLAY AREA"/>
            </g:layer>
        </g:LayoutPanel>
    </g:east>

    <!-- DOCK PANEL NORTH -->
    <g:north size="110">

            <g:layer left="0px" width="755px" top="0px" height="105px">
                    <g:InlineLabel styleName="{style.labeliii" text="NORTH PANEL"/>
            </g:layer>
        </g:LayoutPanel>
    </g:north>

    <!-- DOCK PANEL SOUTH -->
    <g:south size="20">
        <g:LayoutPanel styleName="{style.southPaneliii">
            <g:layer left="0px" width="755px" top="0px" height="20px">
                    <g:InlineLabel styleName="{style.labeliii" text="SOUTH PANEL"/>
            </g:layer>
        </g:LayoutPanel>
    </g:south>

    <!-- DOCK PANEL CENTER -->
    <g:center>
        <g:SimpleLayoutPanel ui:field="mainPanel" />
    </g:center>
</g:DockLayoutPanel>

Answer 1

GWT Place s,PlaceController and PlaceHistoryMapper 您能够在其申请中设立可记名的URLs,使浏览器能够按预期使用。这就是《WT。设计了s。因此,拥有不止一个<条码>是不明智的。地址:在申请时间的任何时候启动,因为所有申请都有一个URL。

<代码>PlaceController sgoTo(> >方法的确通知了已登记的ActiveManager,该编码在收到ChangeEvent后即停止了目前的活动。

My suggestion for you is not to use Places and PlaceChangeEvents for the two areas on the east side of your DockLayoutPanel. Use Places for your application s main screen, which is probably the center of your DockLayoutPanel. Fire different GwtEvent types, either one of the generic event types (ie. ValueChangeEvent) or a custom event type, for the areas on the east side when you need to have them updated. You could still use Activities for the east side, but you would need to create your own ActivityManager, which is actually not that hard. All you have to do is to copy GWT s ActivityManager, rename it, and replace the names of methods that handle PlaceChangeEvents and PlaceChangeRequestEvents with those that handle your own events.

你们是否真的希望使用权宜之计? 使用mvp4g执行这一机制是容易的。主要模块将负责初步确定主要观点,并提供重载动态地区的逻辑。我在两个大型项目中利用了这一框架,并像一个药店一样工作。
