I have a uitable with 6 row and 6 column and i want to show it in full screen mode for doing this i can change column width but i can't change row height.
Extent is Size of uitable rectangle, but it is read only properties.
With conventional approaches the only possibility to change the row height is by adjusting the 'FontSize' property.
The following function will give you a full-screen table. You can set up 'ColumnWidth' and 'FontSize' until it fills your screen entirely.
function fancyTable
columnwidth = { 1920/2 1920/2 };
FontSize = 135;
h = figure('units','normalized','Position',[0 0 1 1],...
'numbertitle','off','MenuBar','none');
defaultData = rand(5,2);
uitable(h,'Units','normalized','Position',[0 0 1 1],...
'Data', defaultData,...
'ColumnName', [],'RowName',[],...
'ColumnWidth', columnwidth,...
'FontSize', FontSize,...
'ColumnEditable', [false false],...
'ColumnFormat', {'numeric' , 'numeric'});
end
I don't see a simple solution to change the row-height independently from the font size.
But there are some ideas at undocumented Matlab.

Could be a fiddly workaround, and there are no code-examples.
You can e.g. use the findjobj utility from the file exchange.
It will get you to the underlying java object of the table, somewhere along the lines of:
t = uitable(...);
scrollPane = findjobj(t);
% not 100% sure about this, but there'll be a `UITablePeer` object somewhere within that scrollPane
jTable = scrollPane.getComponent(0);
This jTable will have a setRowHeight method inherited from http://docs.oracle.com/javase/7/docs/api/javax/swing/JTable.html

I have a Matlab script that creates a Model Block for each element i found in a text file.
The problem is that all Models are created on each other in the window. So i'm trying to make a loop like:
for each element in text file
I add a Model block
I place right to the previous one
end
So it can look like this:
As you can see on the left, all models are on each other and I would like to place them like the one on the right.
I tried this:
m = mdlrefCountBlocks(diagrammeName)+500;
add_block('simulink/Ports & Subsystems/Model',[diagrammeName '/' component_NameValue]);
set_param(sprintf('%s/%s',diagrammeName,component_NameValue), 'ModelFile',component_NameValue);
size_blk = get_param(sprintf('%s/%s',diagrammeName,component_NameValue),'Position');
X = size_blk(1,1);
Y = size_blk(1,2);
Width = size_blk(1,3);
Height = size_blk(1,4);
set_param(sprintf('%s/%s',diagrammeName,component_NameValue),'Position',[X+m Y X+Width Y+Height]);
Inside the loop but it returns an error Invalid definition of rectangle. Width and height should be positive.
Thanks for helping!
The position property of a block does actually not contain its width and height, but the positions of the corners on the canvas (see Common Block Properties):
vector of coordinates, in pixels: [left top right bottom]
The origin is the upper-left corner of the Simulink Editor canvas before any canvas resizing. Supported coordinates are between -1073740824 and 1073740823, inclusive. Positive values are to the right of and down from the origin. Negative values are to the left of and up from the origin.
So change your code to e.g.:
size_blk = get_param(sprintf('%s/%s',diagrammeName,component_NameValue),'Position');
set_param(sprintf('%s/%s',diagrammeName,component_NameValue),'Position', size_blk + [m 0 0 0]);
I followed the procedures in this question, and also tried setting individual text object with larger fonts. Here is my sample code:
hf = figure;
set(hf, 'DefaultAxesFontSize', 14)
hx = axes('Parent',hf);
[hx,hp1,hp2] = plotyy(hx, rand(10,1),rand(10,1),rand(10,1),rand(10,1),'scatter');
hlx = xlabel(hx(1), 'Only half of this line show up');
hl1 = ylabel(hx(1), 'Not usually truncated but less border');
hl2 = ylabel(hx(2), 'Only part of this line show up');
ht = title(hx(1), 'Too close to border');
As can be seen in the picture, the labels get truncated by the border of the figure. I have to drag the figure to very large - contrary to desired - in order to reveal all text.
How can I automatically set the text box according to the text font size, so that even for small graphs they don't get cut?
I know I can do it manually by setting Position of the axes but it's kind of manual and guess-and-try. Is there any automatic way to calculate the margins?
One thing that can be done is to calculate increased margin according to new text font size. Assume we know Matlab's default font size is 10, or otherwise get it by get(hf,'DefaultAxesFontSize').
Then get the relative position of the axes by get(hx, 'Position'), which gives four percentage values. First two define left and bottom margin. Since it's for the labels, increasing the font size from 10 to 14 means the text box should grow by 1.4 times. The next two numbers define the size of the axis. Since text boxes on both sides grow by 1.4 times, assuming original size being x, then new size is 1-[(1-x)*1.4] = 1.4x - 0.4.
Suggested workaround:
hf = figure;
set(hf, 'DefaultAxesFontSize', 14)
hx = axes('Parent',hf);
set(hx, 'Position', [1.4 1.4 1.4 1.4].*get(hx, 'Position')+ [0 0 -.4 -.4])
[hx,hp1,hp2] = plotyy(hx, rand(10,1),rand(10,1),rand(10,1),rand(10,1),'scatter');
hlx = xlabel(hx(1), 'Only half of this line show up');
hl1 = ylabel(hx(1), 'Not usually truncated but less border');
hl2 = ylabel(hx(2), 'Only part of this line show up');
ht = title(hx(1), 'Too close to border');
You may replace the manually entered number 1.4 with the ratio between newly assigned (bigger, hopefully) font size and the original size which is 10.
I would like to programmatically (or in GUIDE) fix the matlab-uitable to be the whole width of the panel on initialisation. How can I do this?
All I've managed is to change the size in pixels of single columns. I would like the uitable to be 100% the width of the page at that time. When my window is in minimized form the GUI looks fine, but when I maximize it, the uitable is only about half the width of the page. (The uitable's height is not that of the whole panel though, around 1/2 of the whole page)
The GUI is written in matlab-guide.
This is the code that I am trying right now:
data = populateTable;
parentPosition = get(handles.uipanel4, 'position');
uitablePosition = [x y parentPosition(3)-2 parentPosition(4)-2];
set(handles.uitable, 'Position', uitablePosition);
set(handles.uitable, 'Visible', 'on');
set(handles.uitable, 'Data',data, 'ColumnFormat',{'numeric'});
A possible solution could be to set both the position of the figure and of the table to normalized, then to set the position of the table to [0 0 1 1]
f = figure
set(f,'unit','normalized')
set(f,'position',[0.1 0.1 0.5 0.5])
data = rand(13);
for i=1:length(data)
col_names{i}=['Col. # ' int2str(i)];
end
for i=1:length(data)
row_names{i}=['Row. # ' int2str(i)];
end
t = uitable(f, 'Data', data,'unit','normalized', ...
'Position', [0 0 1 1],'columnname',col_names, ...
'rowname',row_names);
You need to set the uitable's position property when you initialize it.
First, get the position of the uitable's parent object. That could be a uipanel or a figure. Assume hParent is a handle to the uitable's parent.
parentPosition = get(hParent, 'position');
Then, create your position vector for the new uitable, and use the parent's width and height. You might want to subtract a few pixels for padding. I'll subtract two pixels here.
uitablePosition = [x y parentPosition(3)-2 parentPosition (4)-2];
You can probably set x and y to 1 or 2 as well, depending on where the table is positioned.
uitable( ... 'units','pixels','position', uitablePosition )
You can implement the same idea in your figure's resize function.
I am writing a GUI in MATLAB (guide) where user will be shown 2 images(both images are positioned side by side in single gui window) from a series of images (but each drifted little bit) and will be allowed to select area of interest.
I want user to select working are in image 1 while simultaneously highlighting the selected area in image 2, so that it is easier to judge whether the feature of interest has drifted out of selected area or not. How to do that?
I am using following answer to select and crop area of interest(just FYI):
crop image with fixed x/y ratio
Here is a way to do it using imrect and its addNewPositionCallback method. Check here for a list of available methods.
In the following figure I create 2 axes. On the left that's the original image and on the right that's the "modified" image. By pressing the pushbutton, imrect is called and the addNewPositionCallback method executes a function, called GetROIPosition that is used to get the position of the rectangle defined by imrect. At the same time, in the 2nd axes, a rectangle is drawn with the same position as that in the 1st axes. To be even more fancy you can use the setConstrainedPosition to force the rectangle to be enclosed in a given axes. I'll let you do it :)
Here is the whole code with 2 screenshots:

Yay! Hope that helps! Nota that since you're using GUIDE the syntax of the callbacks will look a bit different but the idea is exactly the same.
I'm working on a gui and using GUIDE. It loads and image and has the user draw an ROI around a point (the particle ROI). I would then like to have two sliders for creating a second ROI (the Scan ROI) where the user can use sliders to set the width and height of the second roi and see it updated on the image. The sliders seem to work ok but my gui keeps drawing a new roi on top of the image so it gets messy looking really fast. I would like to remove the user sizeable roi from the image before redrawing it (while still keeping the original particle ROI on the image. I currently do it the following way :
Inside the callback for the setroi size button (this should be for the particel ROI)
handles=guidata(hObject);
particleroiSize=imrect;% - draw a rectagle around the particle to get a meausr eof ROI size
roiPoints=getPosition(particleroiSize); %-get tha parameters fo the rectanlge
partX1 = round(roiPoints(1));
partY1 = round(roiPoints(2));
partX2 = round(partX1 + roiPoints(3));
partY2 = round(partY1 + roiPoints(4)); % these are the ROi positions in pixels
roiHeight = round(roiPoints(3)); % - these are just the ROI width and height
roiWidth = round(roiPoints(4));
handles=guidata(hObject); %_ update all the handles...
handles.partX1=partX1;
handles.partX2=partX2;
handles.partY1=partY1;
handles.partY2=partY2;
handles.roicenterX = (partX1 + round(roiPoints(3))/2);
handles.roicenterY= (partY1 + round(roiPoints(4))/2);
handles.roiHeight = roiHeight;
handles.roiWidth = roiWidth;
current_slice = round(get(handles.Image_Slider,'Value'));
particleImage=handles.Image_Sequence_Data(partY1:partY2,partX1:partX2,current_slice);
handles.particleImage=particleImage;
set(handles.RoiSizeDisplay,'String',strcat('Particle ROI is ',' ',num2str(roiHeight),' ', ' by ',num2str(roiWidth)) );
guidata(hObject,handles);
And then inside the call back for the sliders that set the Scan ROI size I have (this is inside two different sliders one adjusts the width and one the height :
handles=guidata(hObject);
try
delete(handles.ScanArea);
% plus any cleanup code you want
catch
end
WidthValue = get(handles.ScanAreaSliderWidth,'value');
HeightValue = get(handles.ScanAreaSliderHeight,'value');
set(handles.ScanAreaWidthDisplay,'String',strcat('Scan Area Width is ',' ', num2str(WidthValue))); % sets the display..now to do the drawing...
%h = imrect(hparent, position);
%position = [Xmin Ymin Width Heigth];
position = [ round(handles.roicenterX-WidthValue/2) round(handles.roicenterY-HeightValue/2) WidthValue HeightValue];
handles.ScanArea = imrect(handles.Image_Sequence_Plot,position);
%h = imrect(hparent, position)
handles=guidata(hObject);
guidata(hObject, handles);
But it never deletes the scan area ROI and keeps redrawign over it..I thought the try...catch would work but it doens't seem to. Am I making extra copies of the ROI or something? Please help..
Thanks.
If you need to delete the ROI drawn with imrect, you can use findobj to look for rectangle objects (which are of type "hggroup") and delete them:
hfindROI = findobj(gca,'Type','hggroup');
delete(hfindROI)
and that should do it. Since you first draw particleroiSize, which is of the hggroup type as well, you might not want to delete all the outputs from the call to findobj. If there are multiple rectangles in your current axis, then hfindROI will contain multiple entries. As such you might want to delete all of them but the first one, which corresponds to particleroiSize.
I hope i got your question right. If not please ask for clarifications!
Thanks. This worked perfectly except that I had to use
hfindROI = findobj(handles.Image_Sequence_Plot,'Type','hggroup');
delete(hfindROI(1:end-1))
to get rid of everything but the first ROI, so I guessteh hggoup objects are added at the start ? (I thought I would use deleted(hfindROI(2:end)) to delete all but the first. Also, why does hfindROI return a list of numbers? Do they represent the hggroup objects or something like that?
thanks..
