[英]Layout syntax of an Edit Field component in MATLAB App Designer in a grid parent
我想在 MATLAB App Designer 中創建后立即在編輯字段的網格中指定布局。
app.villes1 = uieditfield(app.GHIetPOA_grid, 'text', 'HorizontalAlignment', 'center', ...
'Editable', 'on', 'Layout', **???**);
我嘗試簡單地使用 [r,c] 但這種語法似乎不正確。 我在谷歌上搜索了我的問題,這是通過創建編輯字段並通過點索引指定行和列來指定行和列的唯一方法:
app.villes1.Layout.Row = 2;
app.villes1.Layout.Column = i+2;
但是,我不能使用它,因為我實際上是在 for 循環中生成編輯字段,並且禁止點索引以這種方式:
function initVilles1(app)
for i=1:8
app.villes1(i) = uieditfield(app.GHIetPOA_grid, 'text', 'HorizontalAlignment', ...
'center', 'Editable', 'on');
app.villes1(i).Layout.Row = 2;
app.villes1(i).Layout.Column = i+2;
end
end
已經謝謝了! (:
你需要初始化villes1
作為陣列gobjects
。
請參閱圖形數組。
例子:
properties (Access = private)
GHIetPOA_grid matlab.ui.container.GridLayout
villes1 = gobjects(1, 8);
end
我只能猜測您使用了以下語法: villes1 = zeros(1, 8);
上面的語法創建了一個double
元素數組。
然后app.villes1(i) = uieditfield(...)
創建一個“舊式”數字句柄,而不是創建一個對象。
使用數字句柄時禁止點表示法。
您需要使用以下語法: villes1 = gobjects(1, 8);
.
現在點索引應該可以工作了。
這是完整的代碼(包括生成的代碼):
classdef app1 < matlab.apps.AppBase
% Properties that correspond to app components
properties (Access = public)
UIFigure matlab.ui.Figure
end
properties (Access = private)
Panel matlab.ui.container.Panel
GHIetPOA_grid matlab.ui.container.GridLayout
villes1 = gobjects(1, 8);
end
methods (Access = private)
function initVilles1(app)
for i=1:8
app.villes1(i) = uieditfield(app.GHIetPOA_grid, 'text', 'HorizontalAlignment', ...
'center', 'Editable', 'on');
app.villes1(i).Layout.Row = 2;
app.villes1(i).Layout.Column = i+2;
end
end
end
% Callbacks that handle component events
methods (Access = private)
% Code that executes after component creation
function startupFcn(app)
% Create Panel
app.Panel = uipanel(app.UIFigure);
app.Panel.Title = 'Panel';
app.Panel.Position = [42 198 1026 464];
% Create GridLayout
app.GHIetPOA_grid = uigridlayout(app.Panel);
app.GHIetPOA_grid.RowHeight = {'1x', '1x', '1x', '1x', '1x', '1x', '1x', '1x', '1x', '1x'};
%app.villes1 = uieditfield(app.GHIetPOA_grid, 'text', 'HorizontalAlignment', 'center', 'Editable', 'on');
initVilles1(app);
end
end
% Component initialization
methods (Access = private)
% Create UIFigure and components
function createComponents(app)
% Create UIFigure and hide until all components are created
app.UIFigure = uifigure('Visible', 'off');
app.UIFigure.Position = [100 100 1118 692];
app.UIFigure.Name = 'UI Figure';
% Show the figure after all components are created
app.UIFigure.Visible = 'on';
end
end
% App creation and deletion
methods (Access = public)
% Construct app
function app = app1
% Create UIFigure and components
createComponents(app)
% Register the app with App Designer
registerApp(app, app.UIFigure)
% Execute the startup function
runStartupFcn(app, @startupFcn)
if nargout == 0
clear app
end
end
% Code that executes before app deletion
function delete(app)
% Delete UIFigure when app is deleted
delete(app.UIFigure)
end
end
end
