我想附加一个 Logo 或更改 App Designer uifigure
的整个背景。如何做到这一点?
最佳答案
如果要为整个图形设置纯色背景,存在a documented way这样做,例如:
% When creating a new uifigure: fig = uifigure('Color',[R G B]) % if the uifigure already exists: fig.Color = [R G B];
- 如果你想改变某个区域的背景颜色,你可以添加一个没有标题或边框的
uipanel
(uipanel(..., 'BorderType','none','Title','','BackgroundColor',[R G B])
). 如果您想将一张图片设置为整个图的背景:
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:
如果您想将图像设置为某个区域的背景:
function q41602238b %% Turn off some warnings: warning off Matlab:structOnObject warning off Matlab:HandleGraphics:ObsoletedProperty:JavaFrame %% 0. Create a some element: app = uifigure(); pnl = uipanel(app); %% 1. Get a handle to the webwindow: while true try win = struct(struct(app).Controller).Container.CEF; % disp(win.URL); break catch pause(0.1); % Give the figure (webpage) some more time to load end end %% 2. Find the id of the DOM element we want to edit: data_tag = char(struct(pnl).Controller.ProxyView.PeerNode.getId); widgetId = win.executeJS(['dojo.getAttr(dojo.query("[data-tag^=''' data_tag ''']")[0],"widgetid")']); %% 3. Manipulate the DOM via a JS command dojo_style_prefix = ['dojo.style(dojo.query("#' widgetId(2:end-1) '")[0],']; while true try win.executeJS([dojo_style_prefix '"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
