关于WPF中Popup控件调研报告

调研人：马小峰调研时间：2013.10.11videoconference, Secretary of the provincial Committee of Xia Baolong stressed: this year is the "five water treatment" "357" timetables "for three years to resolve outstanding issues, obviously worked," victory of the year. The County's departments at all levels must firmly establish the "guanghui is gold and silver" green development concept, convinced that Castle is not relaxed, always maintaining strategic ability and strong determination to improve the environment, consistently playing well "five water treatment of" winning the war, ever-higher levels of comprehensive well-off society was built. (A) lay the sewage uphill battle. This year we will "river water quality improved at the county level, up to five" this basic objective grasp of pollution control that focus, with the focus on three things: a good job, "clear rivers" reaching the County created. Organization "look back" special inspection, the County garbage River, black and odorous River is "Dragnet" investigation, timely

rectification of problems found in place firmly to prevent river pollution rebound. In accordance with the "one-stop strategy", improving the inferior five water quality monitoring stations work this year to ensure the Elimination of 1 provincial control, five water quality section 3 municipalities controlled deterioration, ensure the creation this year of "clear rivers" standards. Second, pay special attention to pollution-cutting construction of nanotubes. Intercepting nanotubes are the basis of pollution of water source engineering, engineering, matter of success or failure of water management. Urban sewage treatment, to improve "effluent from sewage treatment rate, running accuracy, compliance" requirement, speed up the town's support network construction, is focusing on nanotubes home "last meters" question. Domestic sewage treatment in rural areas, this year is the final year of the three-year action, determination to fight and the momentum around, ending the battle on which

fully to ensure the realization of all County 648 formed village coverage. Also, be sure to attach importance to focus on rural domestic wastewater treatment facility operation and management, ensure that wastewater treatment facility up and running, role play, avoid the "Sun" problem. Third, pay special attention to the River Lake pond desilting operation. Provinces now have focused on pollution control of water go to "dig up mud", as the deepening water of this year's "plays". Next, to jump-start an investigation line touches work, implementation plan according to the priorities and the programme of work, in accordance with the "one river one policy" requires detailed cleaning, dredging plan, planning ahead of time cleaning out mud "way out", according to local conditions to do sludge, promote scientific resource utilization of silt and mud. (B) the heavy regulation of heavily polluting industries. Pollution of water must grab the source, wastewater is primarily the source of

backward production capacity, increase the intensity of关于popup控件的调研报告1．控件功能概述Popup控件是一个在和WPF中都涉及到的控件，该报告只针对WPF中Popup控件的功能和属性特点进行调研总结。Popup控件提供一种在单独窗口中显示内容的方法，该窗口相对于指定元素或屏幕坐标浮动于当前应用程序窗口之上。Popup控件可以弹出任意WPF控件表现的内容，即可以包含任意WPF的控件。Popup控件常用来制作自定义的MessageBox，WaitingBox等。属性名PopupAnimation属性用法指示显示窗口时是否使用动画,只有在 AllowsTransparency 等于true时此属性才有用AllowTransParencyStaysOpen设置是否允许透明一个布尔值,指示在

Popup 控件的显示Popup 控件失去焦点的时候,是否关闭

IsOpenPlacementTarget一个布尔值,指示 Popup 控件是否已经显示设定 Popup 定义所相对的控件,如果没有为属性为 NULL,则

Popup 定位相对于屏幕的左上角PlacementRectangle在 Popup 控件显示时,位置将相对于此矩形来显示,此矩形的位置也相对于 PlacementTarget 属性所设定的控件treatment of heavily polluting industries. According to municipal, and municipal government deployment of seven big heavy pollution industry regulation "three years action plans", requirements to December 2016 end of Qian, all included shut stopped eliminated of enterprise all shut stopped eliminated in place; June 30, 2017 Qian, all included place regulation upgrade and agglomeration restructuring of enterprise by unified standard regulation in place, late not standard of enterprise are implementation discontinued; June 30, 2018 Qian, all intends Park production of enterprise relocation Park in place, late not Park of are discontinued. In the process of renovation, will focus on four aspects: to firmly close the high energy consumption and heavy pollution, hopeless enterprise governance and production lines, eliminated a number of yearly emission intensity, low value-added products of backward production capacity. Second, we must strictly enforce the space, total project "Trinity"

environment access system, promoting industry access and environmental conditions of access of enterprises to the Park, industrial park, in principle, no longer the class on the new project. Thirdly, promoting replacement and reconstruction of heavily polluting industries, mergers and reorganizations, guide enterprises to energy conservation, recycling and low-carbon and clean production, and improve the level of green development. Four to establish a long-term supervision mechanism, increase the intensity of special inspections, investigate and punish the rectification is not in place, normal business of running anti-pollution installations do not. (Iii) linkage to promote flood control water, drainage, water supply, improving water saving. Speed up cross Yang support river dike reinforcement, and along Pu seawall except insurance reinforcement, and Lake Qian sluice, and BA Cao sluice, and cloud cover reservoir, focus flood control drainage engineering construction, vigorously

Vigorously implement the piers, algae and other water sources protection and, promoting rural drinking water safety projects, setting up water pricing reform and environmental protection mechanism, guiding water depth. Further soil pollution and repair, strengthen agricultural non-point source pollution prevention, mountain, water, forests, fields, lakes, various elements mutual long. Four, manage to tighten control, to play "three to split" battle. Xia Baolong, Secretary of provincial party Committee stressed that while the "three to split" operation time is over three years, but "three to split" must continue to catch on, and resolve a split cannot be changed.

指定一个值,指示 Popup 的位置所需水平移动多少个象素指定一个值,指示 Popup 的位置所需垂直移动多少个象素三．功能特性Popup 控件提供用于自定义其行为和外观的功能。例如，您可以设置打开和关闭行为、动画、透明度以及 Popup 的大小和位置。打开和关闭行为当 IsOpen 属性设置为 true 时，Popup 控件显示其内容。默认情况下，Popup

的stayopen属性会使Popup保持为打开状态（默认为True），除非 IsOpen 属性设置为 false。不过，您可以通过将 StaysOpen 属性设置为 false 来更改默认行为。当您将该属性设置为 false 时，Popup 内容窗口将获得鼠标捕获。当鼠标事件发生在 Popup

窗口外时，Popup 将失去鼠标捕获并且该窗口将关闭。动画Popup 控件为通常与淡入和滑入之类的行为关联的动画提供内置支持。可以通过将

PopupAnimation 属性设置为一个 PopupAnimation 枚举值来打开这些动画。若要使

Popup 动画能够正常运行，您必须将 AllowsTransparency 属性设置为 true。透明度Popup 控件的 Opacity 属性对其内容没有影响。默认情况下，Popup 内容窗口是不透明的。若要创建一个透明的 Popup，请将 AllowsTransparency 属性设置为 的大小默认情况下，Popup 自动调整大小以适合其内容。由于为 Popup 内容定义的屏幕区域的默认大小的空间有限，不能为要显示的位图效果提供足够的空间，因此在自动调整大小时，某些位图效果可能会隐藏。当然Popup控件也支持手动设置窗口大小（通过treatment of heavily polluting industries.

All localities and

departments to the village and "no unauthorised" createdHeight和Width设置，注意：设置的窗口大小不恩能够小于Popup显示内容本身大小，否则会看不到Popup窗口弹出）。如果在内容上设置 RenderTransform，Popup 的内容也可能会被遮挡住。在这种情况下，如果转换的 Popup 的内容超出了原始 Popup 的区域，则某些内容可能会隐藏。如果位图效果或转换需要较多的空间，则您可以在 Popup 内容周围定义一个边距，从而为该控件提供更多的区域。Popup 的位置您可以通过设置

PlacementTarget、PlacementRectangle、Placement、HorizontalOffset

VerticalOffset 属性来定位 Popup。Popup控件的AllowDrop属性不起作用，即不能实现拖拽。一旦位置定下来就不能和

移动。popup的事件Popup控件具有Opened和Closed两个事件，用以在执行Popup窗口打开和关闭的提示或其他操作。四．代码示例XMAL代码： Button
