如果您想为整个 figure 设置纯色背景颜色,则存在一种记录方法来执行此操作,例如:
% When creating a new uifigure: fig = uifigure('Color',[R G B]) % if the uifigure already exists: fig.Color = [R G B];
- 如果您只想更改某个区域的背景颜色,您可以添加一个
uipanel
不带标题或边框的 (uipanel(...,'BorderType','none','Title','','BackgroundColor',[R G B])
)。 如果要将图像设置为整个图形的背景:
function q41602238a %% Turn off some warnings: warning off Matlab:structOnObject warning off Matlab:HandleGraphics:ObsoletedProperty:JavaFrame %% 0. Create a uifigure: app = uifigure(); %% 1. Get a handle to the webwindow: while true try win = struct(struct(app).Controller).Container.CEF; break catch pause(0.1); % Give the figure (webpage) some more time to load end end %% 2. Find the data_tag of the DOM element we want to edit: data_tag = char(struct(app).Controller.ProxyView.PeerNode.getId); %% 3. Manipulate the DOM via a JS command while true try win.executeJS(['dojo.style(dojo.query("[data-tag^=''' data_tag ''']")[0],"background-image","url(https://upload.wikimedia.org/wikipedia/commons/8/80/Wikipedia-logo-v2.svg")']); break catch pause(0.1); % Maybe JS is still not ready. end end
结果:

不幸的是,我还不能发表评论,所以这是另一个答案。
从 Matlab 2017a 开始,控制器不再具有 Container 属性。这有效:
warning off Matlab:structOnObject
warning off Matlab:HandleGraphics:ObsoletedProperty:JavaFrame
win = struct(struct(struct(app).Controller).PlatformHost).CEF;
data_tag = char(struct(app).Controller.ProxyView.PeerNode.getId);
win.executeJS(['dojo.style(dojo.query("[data-tag^=''' data_tag ''']")[0],"background-image","url(https://upload.wikimedia.org/wikipedia/commons/8/80/Wikipedia-logo-v2.svg")']);
也有可能找到所有活动的网络窗口使用
webWindows = matlab.internal.webwindowmanager.instance.findAllWebwindows();
不幸的是我还没有找到,哪个窗口属于哪个 UIFigure(您可以使用 Title 或 Position 进行过滤,但是两个相同的 UIFigure 会导致问题)。
