Could someone please assist:
Is there a way to change font size of classregtree in matlab?
How can I change the class labels?
Well, try this:
using an example from the docs:
load fisheriris;
t = classregtree(meas,species,...
'names',{'SL' 'SW' 'PL' 'PW'})
I was able to get the property-inspector:
tr=view(t)
inspect(tr)
..what didnt help a lot...
Now I took the handles of all children of tr, that are text-elements:
allHandles=findall(tr,'Type','text')
Next, I just changed the FontSize:
set(allHandles,'FontSize',16)
and there you go :) it is working!
To see and edit other properties, you could now use the inspect-method, as I was doing at my first try, but with the text-handles of course. normally, there should be all other properties available as for normal text-elements. Just check the docs for uicontrol + text.
Lucius's answer worked for me but instead of
tr=view(t)
I had to run this:
before = findall(groot,'Type','figure'); % Find all figures
view(t,'Mode','graph')
after = findall(groot,'Type','figure');
tr = setdiff(after,before); % Get the figure handle of the tree viewer
inspect(tr)

Still learning QGIS using Python, but getting there...thanks to this site!
I'm trying to extract the CRS of the GRID that my layout is using. I think the Class I need to use is QgsLayoutItemMapGrid but can't get there from my testing:
projectInstance = QgsProject.instance()
projectLayoutManager = projectInstance.layoutManager()
# I checked and mine is the 'first' layout, viz [0]
mylayout = projectLayoutManager.layouts()[0]
# found this method in the API reference, but doesn't seem to have CRS etc
mygrid = mylayout.gridSettings()
... but I can't get beyond this. Maybe a different starting point? Any tips? Thanks.
2 problem with minspantree.m in Matlab 2018a
Hi dear all; I want to find a min-span-tree of a matrix. I figured that MATLAB's own minspantree.m may be the most efficient algorithm. So i use
open minspantree.m
And here comes Question:
1.The code in minspantree.m used G.EdgeProperties.Weight and G.Underlying. G is a graph object. But when I use G.EdgeProperties.Weight or G.Underlying in Command window, both returns error: Error using graph/subsref (line 15) No public property 'EdgeProperties' for class 'graph'. Why?
2.minspantree.m line 62：
[pred, edgeind] = primMinSpanningTree(G.Underlying, w, rootNode, restart);
Is primMinSpanningTree a function? But I can not find any: function [ ] = primMinSpanningTree() in minspantree.m, neither can I find primMinSpanningTree.m file in my whole disk. So what is primMinSpanningTree? What is its code? How can I find it and open it?
Thanks all very much.
Both EdgeProperties and Underlying are private properties of the graph class. They can only be accessed from within the class. Take a look at Graph.m. minspantree is a class method, so it has access.
primMinSpanningTree is a built-in method from matlab.internal.graph.MLGraph. You can see that with which primMinSpanningTree. So I believe the code might not be accessible.
After moving pictures in VBA using Shape.IncrementLeft and Shape.IncrementTop I would like to move pictures in openoffice.org BASIC code.
After searching internet with these keywords "move picture" and "openoffice.org" or "open BASIC" or "OOo BASIC" I did not find the answer.
I have found how to move pictures in Java, c++, android, but not in OpenOffice.org BASIC,
I read trough these guides
https://wiki.openoffice.org/wiki/Documentation/BASIC_Guide
http://www.pitonyak.org/OOME_3_0.pdf
I tried to find the answer through LIBRE OFFICE also, but without success.
I tried to record a macro, insert a picture, move it with the mouse and stop the macro.
When looking into the code, the answer of my question take me to the dispatcher and one of the UNO methods, I believe is has something to do with these keywords:
Properties in the com.sun.star.awt.UnoControlImageControlModel service
com.sun.star.drawing.GraphicObjectShape
BorderBottom
BorderLeft
BorderRight
BorderTop
oPoint = oShape.Position
getPosition()
setPosition(Point)
but I cannot find a clear answer and I do not know how to combine them to make the image (or it can be a shape inserted also) to move.
can anybody guide me how to find the answer?
first of all: https://wiki.openoffice.org/wiki/Extensions_development_basic is a good starting point. In particular the XRAY tool is very helpfully.
The following Code changes the position of a selected Image on a Calc Worksheet:
Sub Test
dim aNewPosition as new com.sun.star.awt.Point
oDoc = thisComponent
oSelection = oDoc.CurrentSelection(0)
if oSelection.supportsService("com.sun.star.drawing.Shape") then
aPosition = oSelection.Position
x = aPosition.X
y = aPosition.Y
aNewPosition.X = x + 100
aNewPosition.Y = y + 100
oSelection.setPosition(aNewPosition)
endif
End Sub

I am trying to keep track of the current Y position on a PDF page created using FPDF so that I can correctly start a new page ensuring tables do not cross a page break. Firstly am I right in using GetY to monitor this and if so what is the correct syntax. I am trying
$currentYposition = GetY();
but it does not seem to work. Any advice?
No idea why this works - but it does:
If you just grab Y after the call, it seems to be the value before the MultiCell.
Grabbing it before and after and taking the difference gives you the height.
$oldY = $this->getY();
$this->MultiCell(150, 4, utf8_decode($description), 0, "L");
$newY = $this->getY();
$multiCellHeight = $newY-$oldY;
This one worked for me.
$y = $pdf->GetY();
I came to this question when programming in python and using the fpdf module. I'll post in case anyone else need this, I could not find this solution in the official documentation but for me following worked:
from fpdf import FPDF
pdf = FPDF()
pdf.add_page()
current_y = FPDF.get_y(pdf)
I am trying to draw a text glyph on the map and all the tutorials say I need a IDynamicDisplay, but I don't know how to get at one. Thanks in advance. ; )
edit: C# VS2010
First you need to set IDynamicMap::DynamicMapEnabled property from Map object to true.
IDynamicMap pDynamicMap = pMap as IDynamicMap;
pDynamicMap.DynamicMapEnabled = true
Then, there are two ways to get DynamicDisplay object. One is creating custom Layer with implement IDynamicLayer interface. Second one is hooking IDynamicMapEvents::BeforeDynamicDraw event or IDynamicMapEvents::AfterDynamicDraw event. I hope this best practice help you.
Best practices for using dynamic display
You have to wire up an event handler
ESRI.ArcGIS.Carto.IDynamicMapEvents_Event dynamicMapEvents = dynamicMap as ESRI.ArcGIS.Carto.IDynamicMapEvents_Event;
ESRI.ArcGIS.Carto.IActiveViewEvents_Event avEvents = activeView as ESRI.ArcGIS.Carto.IActiveViewEvents_Event;
avEvents.AfterDraw += new ESRI.ArcGIS.Carto.IActiveViewEvents_AfterDrawEventHandler(avEvents_AfterDraw);
dynamicMapEvents.AfterDynamicDraw += new IDynamicMapEvents_AfterDynamicDrawEventHandler(dynamicMapEvents_AfterDynamicDraw);
