uitable is probably the most complex basic GUI controls available in Matlab. 'ColumnFormat',({[] [] material_list}), . My code is; jtable.getSortedRowAt(eventData.Indices(1)) The results are incorrect most of the time unfortunately. d = {'Male',52,true;'Male',40,true;'Female',25,false}; t.ColumnName = {'Gender','Age','Authorized'}; I want to set the title for this uitable. Is there another way to get the Java handle to the UITable when its in a UIFigure? Thank you so much. I figured out the answer by further reviewing the long thread in my question. Then the sorting of the numbers is not right. If you want the scroll bar not to jump up to the top and jump back down to the previous position, you can use the following workaround. In order to fix this, do not explicitly set the position of the figure. uit = uitable (Name,Value) specifies property values of the table UI component using one or more name-value pair arguments. Note that my original widths set in GUIDE are [300, 150, 150, 150], so the 75 px numbers do NOT come from my code. Hello guys, I don't really know if this is an efficient way to solve this, but if you substitute "drawnow" for "pause (0)", the scroll position updates will occur faster and instead of a back-and-forth scrolling, the table should just blink once. We have access to a fairly large variety of toolboxes, if that helps, but I do have a requirement to make this a stand alone application with application compiler, so the solution has to be compatible with that toolbox. Some of the data updates every 4.5 seconds. The problem regard the coefficient (frac16 fixed point). In comparison, legacy figures are based on Java desktop windows. It was based on an internal MathWorks extension of the standard Java Swing JTable a class called com.mathworks.widgets.spreadsheet.SpreadsheetTable. This has been a deficiency of JTable for ages. Fogot my last message, I was loading my data erroneously, and that is why I couln't edit it. This works well for UITables embedded in a traditional figure but Im having issues getting findjobj to work when the UITable is embedded in a UIFigure, it just returns an empty array. If the user selects a new cell, then the focus is switched to the view making the selected row now visible again. @Amit unfortunately I only refer to this issue in my report, not the book. :) I really appreciate that! @Dan uifigures are based on HTML and JavaScript, they are basically nothing more than a webpage displayed within a browser window. Doubles are sorted lexically (12 < 6), not numerically (12 > 6). ?CALLBACKHERE# = {@t2_Callback,ht_jtable}; % ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^. ADC 16 (1214 % 2. Try adding one before the "scrollMax=" line and see if that fixes it. In order to fix this, do not explicitly set the position of the figure. Do you have any thoughts? Integers dont exhibit this problem. You can read all about it in my uitable customization report. After many years in which the uitable was available but semi-documented and not officially supported in Matlab, it finally became fully documented and supported in R2008a (aka Matlab 7.6). . It just makes whatever row you interacted with one up from the bottom. . MATLAB: How to control Uitable scroller position, MATLAB: Table scroll position Update problem, Programatically selecting cells in a uitable, Using a JTable, is it possible to move the cursor (highlighted cell) horizontally when pressing enter. @Drew strange indeed. uitable() creates a graphics object that visually represents tabular data. Is it me or doubles are not properly sorted by the new uitable? Add the TableSorter.jar file to your static java classpath (via edit('classpath.txt')) or your dynamic classpath (javaaddpath('TableSorter.jar')). uitable(. You had been a life saver so many times. I am writing a gui that monitors instrument data. I read through the report, and cant seem to find any reference to the workaround for dealing with numbers with the new uitable. If there is no figure available, MATLAB calls the figure function to create one. If youd like me to check this out for you, contact me by email for a short consulting proposal. If youd like me to investigate this (for a consulting fee) then email me. Try playing around with different parameters, maybe move the table a bit in the figure, maybe download the latest version of findjobj. Consider using the Extent property value when specifying the width and height values of the uitable Position property. This property specifies a callback function to execute when MATLAB creates the uitable. Note that both of them are unsupported and undocumented. Using combinations of the last two arguments, you can select any cells you want programatically, even if they're not contiguous. expand all. The code you used already visually displays the random numbers in a tabular form, to about 4 digits. Is there a way to set the scroll position in the table instead of "jumping" every time the table is updated? This is annoying on the 4.5 second data and unusable on the faster data. For details on uifigure customizations, refer to the list of posts that have the uifigure tag. Thanks very much for your response. If yes, is there a way to fix it? ., 'units', 'normalize', 'position',[0 0 1 1]) This line below will only work if the axis units are also normalized and it will place the uitble directly on top of the axis. You can programmatically select a new row, then the focus is switched to the view making the selected row now visible again.The working solution running safely on Java Swings Event Dispatch Thread (EDT) without risking a race-condition or deadlock with the EDT would be: jscrollpane = javaObjectEDT(findjobj(src)); viewport = javaObjectEDT(jscrollpane.getViewport); jtable = javaObjectEDT( viewport.getView ); It requires findjobj functionality, and works fine on Matlab R2017a. After many years in which the uitable was available but semi-documented and not officially supported in Matlab, it finally became fully documented and supported in R2008a (aka Matlab 7.6). % Matlab mat % ADC RX % % % Matlab %================================= JSON % 2017a % % % %========================= % 1. A workaround for sorting numbers in uitable is detailed in the report.

MATLAB converts the value to text and displays it left-justified in the table. Sliding down (once the first cell is at the top) the UITableView would then . If there is no traditional figure available, MATLAB creates one. Programming and Web Development Forums - matlab - The MathWorks calculation and visualization package. The drawable area is the area inside the borders of the . . Are you working on new editions of both of your books? Users will normally try to sort columns by clicking the header. If the user selects a new cell, then the focus is switched to the view making the selected row now visible again. Of course, every time I do this, the uitable automatically resets to focus on the top row of data. Thank you for the suggestions. i read through your undocumented matlab book but didint find. As for numeric sorting, I did not discuss this issue in my book. It turns out that the issue is not because of the title, but rather, because the position of the figure in the window is independent of the uitable, such that when you maximize the window, the figure position gets misaligned with that of the uitable. If there is no traditional figure available, MATLAB creates one. jTable = findjobj (hTable); jScrollPane = jTable.getComponent (0); There are two solutions. Saltar al contenido. The problem is I cant figure out a callback that will fire when the columns are rearranged! @Luc this is correct. uit = uitable (parent) creates the table in the specified parent container. %- % 3. m = numeric handle to uitablem = uitable (. The Position values are relative to the drawable area of the parent container. How do I do this? I understand nothing of the sort is currently supported by matlab, but does anyone know how I can achieve this given access to the underlying java swing object? jScrollpane = findjobj(handles.myuitable); scroll = jScrollpane.getVerticalScrollBar.getValue; jScrollpane.getVerticalScrollBar.setValue(scroll); With this code, every update causes the scroll bar to jump up to the top and jump back down to the previous position. Control the scrollbars, as explained here: http://undocumentedmatlab.com/blog/setting-line-position-in-edit-box-uicontrol/http://undocumentedmatlab.com/blog/customizing-listbox-editbox-scrollbars/, Yair Altman http://UndocumentedMatlab.com. uitable is probably the most complex basic GUI controls available in Matlab. uitable(. https://www.mathworks.com/matlabcentral/newsreader/view_thread/310934/. @Yun I believe that you read the blog post, not the report. To make it more clear its running multiple times on a single cell value, Callback reentrancy is now controlled but still i am getting the java exception exception in thread AWT=EventQueue-0, Hi,Yair I hava a question.when I use jtable.setModel(javax.swing.table.DefaultTableModel(Data,headers)to updata the data in old matlab uitable;I find I cannot use data = cell(mtable.getData)to get the editored data I find use jtable.getModel().getDataVector() can get the data in java.util.Vector .But how I let the the java.util.Vector Data tranfer a cell-style data I try use cell(jtable.getModel().getDataVector()),but the result is [ 1000 java.util.Vector]; Thanks. I don't quite see how this could work with the uitable, and the other article dealt with the Scrollbar policies and line-wrapping, but didn't mention any way to get or set the current scroll position. This is a shame because this kind of filter is what I was looking for! data = cell(mtable.getData) should be used but you might need to pause(0.01) to let the data updates propagate from the jtable model to the mtable object. MATLAB: How to update uitable data without resetting column widths and scroll position, MATLAB: Programatically selecting cells in a uitable, How to deselect ToolbarStateButton without clicking on it, Deactivate ButtonDownFcn ? I understand that when you have a uitable in a figure and you maximize the window for the figure, a "grid" shows up that is partly behind the uitable. I have the same problem with large number of rows. . (I have an application build in App Designer.) MATLAB: How to control Uitable scroller position This workaround solution use again the FEX: findjobj functionality and implicitly sets the selection mode to SINGLE_SELECTION. Is there a way once I've got the Java scroll-pane container reference that I can, 1) Get the current line position corresponding to the top visible row2) Set the scroll position to match that in (1). @Ange mtable.getTable only works on the old (pre-R2008a) uitable; with the new (R2008a onward) uitable you need to use the findjobj utility to get the underlying Java object. In a UITABLE I have many columns of data and would like the width of the columns to be auto-adjusted such that all their content is visible. @shi this is an unhandled case in the ColoredFieldCellRenderer code. However, you can achieve the desired effect by placing a "uicontrol" of style "text" directly above the uitable. Looks like a JIDE bug to me Maybe this is the reason for sorting not being exposed in Matlab. Flutter ListView.builder,flutter,listview,refresh,Flutter,Listview,Refresh It is unusable on the faster data. Can you explain me please what is the meaning of the index that getSortedRowAt is returning? Unfortunately, Matlabs uitable does not have sorting built-in, although its quite easy to add it, as I shall now show. I am slowing the table updates down to about to a few times per second so the values are visible. It works fine on lion. As a workaround in previous MATLAB releases, you can use the following MATLAB function to track mouse motion: % This function creates two static text controls, % which contain the x & y coordinates of the mouse, % The driving callback is executed by the. If all this still doesnt work, you can either debug findjobj step-by-step with the debugger, or use a different sorting mechanism, or implement a pure-Java table. Since R2008a, both versions of uitable are available the old version is available by adding the v0 input arg. This workaround solution use again the FEX: findjobj functionality and implicitly sets the selection mode to SINGLE_SELECTION. %%% t2.#? jscrollpane = javaObjectEDT(findjobj(src)); viewport = javaObjectEDT(jscrollpane.getViewport); jtable = javaObjectEDT( viewport.getView ); jtable.scrollRowToVisible(where_changed - 1); it requires findjobj functionality, and works fine on Matlab R2017a. label;MATLABnamestyletext;titleuicontroluitable. As a last resort, you can always use my consulting skills. tablew = utable.Position(3); %get with of the uitable. Ever seen anything similar? I say it is a partial solution because if the user is in the process of resizing the columns when the data is updated all columns reset to 75 pixels regardless of any previous settings. On snow leopard, placing the sorting code below the one that updates the table seems to do the trick. How to add a sortable property to uitable within a classic figure. when an uitable is updated, uitable automatically resets to focus on the top row of data. So any customization that works on the Java-based figures and relies on Java (including uitable customizations) will never work in uifigures, and you cannot get the Java handle of uifigure components because theyre not based on Java. Because I noticed that after im sorting a table the table.Data remains the same as before i sorted the table and actually disconnect what the table showing to the user. This area excludes the figure borders, title bar, menu bar, and tool bars. The only OS the code works flawlessly from within OutputFcn is Lion. @Jack sorting only affects the way that the table-model data is displayed, it does not affect the data itself. 1 , . , . Also, the report is in full-color PDF format, whereas the book is not. The report includes the following (more details here): Tags: GUI, Hidden property, HTML, Internal component, Java, JIDE, Semi-documented function, uitable, uitools, Undocumented feature, Hello Yair, Without knowing your post, i have posted about this subject at Matlab Newsreader. I have about 75 rows (varies between the different tables) and 4 columns. The uitable function creates a table UI component and sets any required properties before displaying it. System info: Windows 7 64-bit, Matlab r2011a 64-bit. I suggest that you use App Designer to create a scrollable uitable with the data. Here is some updated code that works at least until Matlab R2015b. "coffee_pot" wrote in message
