Does anyone know of a method to display a popup date selection calendar in a MATLAB gui? I know the financial toolbox has a uicalendar function, but unfortunately I don't have that toolbox.
I have a hunch I'm going to have to use some Java or some other language for this one, which I know nothing about.
I'm looking for something similar to this:
(source: welie.com)
which would return a date string after the user selects the date.
Here are two approaches that would give you a professional-looking calendar component in Matlab without too much programming work:
Use a Java calendar component (for example, one of these or these). Once you download the relevant Java class or Jar-file, add it to your static Java classpath (use the edit('classpath.txt') command from the Matlab Command Prompt). Finally, use the built-in javacomponent function to place the component in your Matlab figure window.
If you are using a Windows OS, you can embed any Active-X calendar control that is available. Use the built-in actxcontrolselect function to choose your favorite calendar control (for example, Microsoft Office's "Calendar Control 11.0" - MSCAL.Calendar.7 - which is automatically installed with Office 2003; or "Microsoft Date and Time Picker Control 6.0" - MSComCtl2.DTPicker.2, or ...). Then use the actxcontrol function to place the component in your Matlab figure window.
Matlab has some pretty useful built-in calendar (date-selection) controls - I posted an article about them today
I don't have much time for a more complete answer, unfortunately, but I'd try uitable to create a table and to define the CellSelectionCallback to get the date.
Here's a bit to get you started:
dates = calendar;
dates(~any(dates,2),:) = [];
fh = figure;
uh = uitable('parent',fh,'data',dates,'ColumnWidth',repmat({20},1,7),...
'ColumnName',{'S','M','T','W','T','F','S'});
I'd start with the calendar() function which outputs a matrix containing the calendar for any month. I assume you could combine this with a user-clickable interface to retrieve a specific date?
The following code is really ugly, but could help you get started...
WINDOW_WIDTH = 300;
WINDOW_HEIGHT = 200;
f= figure('Position',[300 300 WINDOW_WIDTH WINDOW_HEIGHT]);
NB_ROWS = 6;
NB_COLS = 7;
width = round(WINDOW_WIDTH/NB_COLS);
height = round(WINDOW_HEIGHT/NB_ROWS);
buttons = nan(NB_ROWS,NB_COLS);
dates = calendar();
for row = 1:NB_ROWS
for col = 1:NB_COLS
if dates(row,col) == 0
mydate = '';
else
mydate = sprintf('%i', dates(row,col));
end
buttons(row,col) = uicontrol('Style', 'PushButton', ...
'String', mydate, ...
'Position', [(col-1)*width (NB_ROWS - row)*height width height]);
end
end

I've just started working with Windows Forms on Visual Studio 2019. I am most familiar with C++ and thus have been creating an application with C++/CLI. The basis of the project is that I have a schedule generating set of functions these are called in MyForm.h which is the main form originally launched. MyForm.h also opens MyForm2.h when a button is pressed. This MyForm2.h is where I have a problem. I want to allow the user to edit a series of specific settings for the schedule generator. The most user friendly way I've found to do this is with a datagrid using textboxes and checkmarks, but I need to have the original timeslots for the schedule in the datagrid for the user to edit when the open MyForm2.h.
I've looked all over to find how to set default values for a datagrid, but have only come up with two ok methods, both of which have some fatal flaws.
The first was from this microsoft guide.
The problem here is that the solution is written in c#, and I don't know how to implement it in a c++ program.
The second was from a few sites which generally displayed one of two formats which are displayed here in a way that is formatted to how I used them in my forms:
void InitializeComponent()
{
this->dgvStudents = (gcnew System::Windows::Forms::DataGridView());
this->dataGridViewTextBoxColumn1 = (gcnew System::Windows::Forms::DataGridViewTextBoxColumn());
(cli::safe_cast<System::ComponentModel::ISupportInitialize^>(this->dgvStudents))->BeginInit();
this->SuspendLayout();
this->dgvStudents->Columns->Add(this->dataGridViewTextBoxColumn1);
this->dgvStudents->Location = System::Drawing::Point(0, 0);
this->dgvStudents->Name = L"dgvStudents";
this->dgvStudents->Size = System::Drawing::Size(350, 100);
this->dgvStudents->TabIndex = 0;
//
// dataGridViewTextBoxColumn1
//
this->dataGridViewTextBoxColumn1->HeaderText = L"First Name";
this->dataGridViewTextBoxColumn1->Name = L"dataGridViewTextBoxColumn1";
this->AutoScaleDimensions = System::Drawing::SizeF(6, 13);
this->AutoScaleMode = System::Windows::Forms::AutoScaleMode::Font;
this->ClientSize = System::Drawing::Size(638, 261);
this->Controls->Add(this->dgvStudents);
this->Name = L"MyForm3";
this->StartPosition = System::Windows::Forms::FormStartPosition::CenterScreen;
this->Text = L"Exercise";
(cli::safe_cast<System::ComponentModel::ISupportInitialize^>(this->dgvStudents))->EndInit();
this->ResumeLayout(false);
// Option 1
this->dgvStudents->Rows[0]->Cells[0]->Value = "MLP";
// Option 2
this->dgvStudents->Rows->Add("MLP");
}
I have tried putting both options in several various parts of the InitializeComponent() function and it makes no difference. The problem with Option 2 of this second solution is that it will be removed from the code if I change anything in the [Design] part of the MyForm2.h code editor in VS and save it. Weirdly, Option 1 will not be displayed in the [Design] part of the code and instead I will get the error Member Cells not found in class System.Windows.Forms.DataGridViewRowCollection, but if I launch the debugger for the program, both options will be displayed exactly how I want them to be in the GUIs that appear. As previously meantioned though, both options will most likely be removed if I change anything else in the form designer. Any help would be greatly appreciated:)
We're using the Telerik (PHP UI) controls but there appears to be something that I'm not able to crack.
We store timestamps in the backend database in UTC, and when using a Grid to display such items, I want to be able to show that UTC timestamp converted into the local users timezone (the TZ data is stored as a PHP variable, different people logging in could be in different TZs). It appears I'm not the only one that's asking this, as the Telerik forum someone else asks the same question but without an answer (scroll to the bottom of that forum post).
From the Telerik site I it appears that all I'd have to do is to format the date with a format with "zzz" appended to the date, but all this does is add the offset to the displayed time (eg 2020-02-27 10:00:00 -> 2020-02-27 10:00:00-0800) ... but it does do this "auto-magically" which I suppose is nice ... (heavy sarcasm)
This forum post also shows that an onRequestEnd call should do what I need it to do, but when I attempt this, nothing appears to change.
Can anyone offer up any advice?
Note : I've created the outer table with the following:
$grid = new \Kendo\UI\Grid('grid');
Solution: I achieved this by adding the following to the page:
function dataSource_requestEnd(e){
var data = e.sender.options.data.data;
for(var i=0; i<data.length; i++){
var td = data[i];
for (var key in td){
if (key === "NameOfDateField"){
var offset = new Date().getTimezoneOffset();
new Date(td[key].setMinutes(td[key].getMinutes() - offset));
}
}
}
}
$(document).ready(function() {
var dataSource = $("#grid").data("kendoGrid").dataSource;
dataSource.bind("requestEnd", dataSource_requestEnd);
dataSource.fetch();
});
Please note that NameOfDateField was the name of the key in the array that was returned from the dataSource.
TBH, I'm not at all sure how the data got converted, but certainly the offset and localTime variables are vital to this succeeding (although to my mind, they don't actually update anything?!)
I have a tkinter interface with a few entry widgets as inputs. Upon clicking a button I would like those inputs to be sent to a separate script to be processed and a value printed and potentially returned back to the button (I am looking at this for a dual accuracy assessment statistic)
This is a lower scale example of what I have so far and am looking to accomplish
Example Secondary Script: GUI_ConnectorScript
def calculate():
global result
result = int(entry.get())
result += 1
print result
Primary Script: GUI_ConnectorScript
from Tkinter import *
import GUI_ConnectorScript
background = "#A8A8A8"
master = Tk()
screen_width = master.winfo_screenwidth()
screen_height = master.winfo_screenheight()
width = int(screen_width*0.7)
height = int(screen_height*0.7)
size = "%sx%s"%(width,height)
master.geometry(size)
master.title("GIS Display")
text = Text(master, width = 80, height = 40, background = background)
text.pack(expand = TRUE, fill = BOTH)
entry = Entry(master, width=5).place(x=100,y=100)
button = Button(master, text="Calculate", command=GUI_ConnectorScript).place(x=500,y=500)
mainloop()
I have been trying to figure this out for awhile and have look around a lot for an answer. I have found examples similar but I am having an issue getting it to work for my application.
I agree with Parviz, whenever GUI programs get too complicated you should use Object-Oriented Programming.
I can further advice that you use kivy (if possible) instead of tkinter, its much better for bigger projects
The company I'm with is likely to obtain an ActiveReports 7 license. There's a new project requirement that several webgrids (not actually webgrids, but more like html rendered with zurb) need to be converted into pdfs. At one point in the code behind they're effectively datasets or can be created into such. Is there a way to shuttle the data from the datasets into active reports, then render it out as a PDF. I'd like to keep the report as generic as possible, and thus have one active report for all the datatables, so doing using active reports as its usually done is kind of out of the question.
The only thing I can think of at the moment is a single textbox in the group header into which I could concatenate all the headers, and a single textbox in the details into which I could throw all the data for each row. The problem here is that I'd run into many formatting issues as nothing would line up properly - as tab delimiting would solve nothing here. I could have multiple textboxes with various spacing, but then it would eventually devolve into a different report for each dataset. Is it possible to apply some sort of markup so that I could keep the spacing of columns as I feed the data in. Do active reports richtextboxes honor html markup? Or is there another solution altogether?
I'd use Itextsharp, but its not free for commercial products.
Thanks,
Sam
You can dynamically build a report that will output a simple table based on a specified DataSet, well actually a System.Data.DataTable. Basically for each column in the DataTable, add a textbox to the header to hold the name of the column and add another textbox to the Detail section to hold the value.
For the textbox in the detail section set its DataField property to the name of the column. With the binding in place, you can set the report's DataSource property to the DataTable and then run the report and export it to PDF.
The following code is a basic example:
var left = 0f;
var width = 1f;
var height = .25f;
var space = .25f;
var rpt = new SectionReport();
rpt.Sections.Add(SectionType.ReportHeader, "rh").Height = height;
rpt.Sections.Add(SectionType.Detail, "detail").Height = height;
rpt.Sections.Add(SectionType.ReportFooter, "rf").Height = height;
foreach (System.Data.DataColumn col in dataTable.Columns)
{
var txt = new TextBox { Location = new PointF(left, 0), Size = new SizeF(width, height) };
txt.Text = col.ColumnName;
rpt.Sections["rh"].Controls.Add(txt);
txt = new TextBox { Location = new PointF(left, 0), Size = new SizeF(width, height) };
txt.DataField = col.ColumnName;
rpt.Sections["detail"].Controls.Add(txt);
left += width + space;
}
rpt.DataSource = dataTable;
rpt.Run();
var pdf = new PdfExport();
pdf.Export(rpt.Document, #"c:\Users\scott\downloads\test.pdf");
I have GUI in Matlab that I have made using the Programmatic approach. It has 6 sliders and I want to be able to move one of them and have the others update as if i clicked them again but to stay in the same place. I am guessing I will need to use the set() function. Is there some function to do this in matlab already? I have been looking around. Any suggestions or something to point me in the right direction?
If you are using guide, you can access the other sliders from the handles variable that is available in each callback.
Set the Value property for them.
function Slider1_CallBack(hObj,evt,handles)
set(handles.Slider1,'Value',10);
set(handles.Slider2,'Value',10);
% etc..
end
In case you are using it programmaticaly, you can store the handles manually.
function main
handles.Figure1 = figure(..);
handles.Slider1 = uicontrol(...);
handles.Slider2 = uicontrol(...);
guidata(handles.Figure1,handles);
end
And your slider callback should be:
function Slider1_CallBack(hObj,evt)
handles = guidata(hObj);
set(handles.Slider1,'Value',10);
set(handles.Slider2,'Value',10);
% etc..
end
Edit A good practice in writing UI is separating the GUI logic from the actual data. You always change the data, and call updateGUI routine.
Therefore, you can write your program like this:
function main
handles.gui.Figure1 = figure(..);
handles.gui.Slider1 = uicontrol(...);
handles.gui.Slider2 = uicontrol(...);
handles.data.x = 1;
guidata(handles.Figure1,handles);
end
function UpdateGui(handles)
%Based on the data, update the GUI
set(handles.Slider1,'Value',handles.data.x);
set(handles.Slider2,'Value',handles.data.x+1);
end
And the callback should look like:
function Slider1_CallBack(hObj,evt)
handles = guidata(hObj);
handles.data.x = handles.data.x + 1;
UpdateGui(handles);
guidata(hObj,handles);
% etc..
end
