How can I get the value of Label?
I'm able to set value using [label setString:[NSString stringWithFormat:#"%d", val]];
Trying to find the reverse of that, i.e grabbing the string value.
Thanks,
Tee
try [label label] or [label string].

I am using YOLOv5s for object detection on custom datasets, there are multiple objects in given video, sometimes label text and bounding box thickness looks very bad. how can I customize these things?
when using detect.py, pass in the following arguments to adjust the labels and bounding boxes:
--line-thickness 1
--hide-labels True
--hide-conf True
For the --line-thickness argument, pass in an integer value to adjust the thickness, for labels and confidence, they are set to False by default. Setting them to True will hide them.
Be careful using --hide-labels True or hide-conf True. Under certain circumstances you can encounter an ErrorMessage. Only --hide-labels and --hide-conf should work perfectly fine.
Here is a list of arguments you can use with detect.py.
detect.py [-h] [--weights WEIGHTS [WEIGHTS ...]] [--source SOURCE]
[--data DATA] [--imgsz IMGSZ [IMGSZ ...]]
[--conf-thres CONF_THRES] [--iou-thres IOU_THRES]
[--max-det MAX_DET] [--device DEVICE] [--view-img]
[--save-txt] [--save-conf] [--save-crop] [--nosave]
[--classes CLASSES [CLASSES ...]] [--agnostic-nms]
[--augment] [--visualize] [--update] [--project PROJECT]
[--name NAME] [--exist-ok] [--line-thickness LINE_THICKNESS]
[--hide-labels] [--hide-conf] [--half] [--dnn]
I've been working in a code for some weeks, just trying to start with python and I've found a strange problem when I try to update the values in a top level window from Tk, the previous value of the label seems to be in the background of the label and I must remove it, here some pics to show the problem, thank you for reading my problem and also for all your help.

PD: it is in spanish
PD2: if the code is needed I can paste the segments of the code that generates this issue.
The problem was generated when I hitted a button in the Tkinter interface, and every time it generated a new Label, this new Label displayed the updated information, but the older ones was still in the frame, then when I changed the value of the StringVar to something shorter I still could see the last Label there, the solution was to destroy the last Label when I update the value of the StringVar socitaed to the Label, then I get what I needed.
The code that generated the error:
self.varTotal = StringVar()
self.lblTotal = Label(self.master, textvariable = self.varTotal)
self.varTotalLetras = StringVar()
self.lblTotalLetras = Label(self.master, textvariable = self.varTotalLetras)
...
self.varTotal.set(total)
self.varTotalLetras.set(num2words(int(total), lang = 'es').upper() + " PESOS.")
Then every time when I clicked the button a new instance of the Label seemed to be created.
And My solution was to delete the current instance of the Labels and then create another one.
I'm trying to insert tag next to specific text.
I was get a knowhow to insert tag next to text..
It is to use Setsel() and ReplaceSel().
example,
char str = "< name >";
m_richedit.Setsel( position of start dragging of text, end position )
m_richedit.ReplaceSel( str, TRUE )
but, I don't know how to get position of start dragging of text in richEdit.
Is there anybody who has an idea?
Thank you.
You need to add the appropriate accelerator key like they explain here: Adding accelerators(shortcuts) in MFC - HOW? . Then in the handler of the accelerator key, use GetSelText, add your tags to the string you get and call ReplaceSel.
I have a bunch of cells whose font size I'd like to tweak if their content is overflowing, until it all fits. I'd like to write a macro to do this, unless there's a conditional formatting or other formulaic way of doing it. Is there a property that tells whether a cell is overflowing? If so, what is it?
'open office 3
'get current document
oDoc = ThisComponent
' get first work sheet
oSheet = oDoc.getSheets().getByIndex(0)
'first cell in the work sheet
Cell = oSheet.getCellByPosition(0, 0)
MsgBox Cell.CharHeight
Happy Coading :))
I have a graph that I show two sets of data in it. The user can hit a button to flip to another set of data. The problem is the axes aren't the same, but when I want to update the ticks I instead just layer on top another axis.
http://jsfiddle.net/scottieb/VjHd6/
The key bit is at the end:
vis.selectAll("axis").remove();
vis.append("svg:g")
.attr("class", "x axis")
.attr("transform", "translate(0, " + (h - margin ) + ")")
.call(d3.svg.axis()
.scale(x)
.tickSize(0)
.tickSubdivide(true)
.tickFormat(formatCurrency)
);
I've tried selectAll("g").remove(), but that prevents laying down the next axis. Any ideas?
Whoops, needed to redefine the scale and call a transition rather than just build a whole new axis.

Your issue is that your selector is not correct. Instead of selecting "axis", you should select ".axis" since you are appending a "g" node with a class.
