While learning Progress 4GL, I stumbled upon following piece of code, assigning a value to an attribute of a widget within a frame:
ASSIGN Rep-Editor:READ-ONLY IN FRAME Dialog1 = YES
Rep-Editor:SENSITIVE IN FRAME Dialog1 = YES.
As you can guess:
Dialog1 is the name of the frame.
Rep-Editor is the name of the widget, placed within the frame.
This looks very confusing to me: it's like saying that the value of the frame equals "YES", I expect the assigned variable and value to be next to each other, something like:
ASSIGN Dialog1.Rep-Editor:READ-ONLY = YES, /* or: */
ASSIGN Dialog1->Rep-Editor:READ-ONLY = YES
This, obviously, is not the right syntax. Is there a Progress syntax, similar to this one, that I can use?
Well ... that’s almost 40 year old ABL syntax ...
You could wrap everything inside a
DO WITH FRAME Dialog1:
ASSIGN Rep-Editor:READ-ONLY = YES
Rep-Editor:SENSITIVE = YES.
END.
block.

With variables such as integer, float or string I used Write To Symbol to write the variable to the PLC with the HMI textbox under .onTextChanged in the properties window (see images below).
But it won't work with the Time variable.
How can I make this work without changing the PLC code?
I've never worked with javascript before, but that is where I found the sollution.
I also used .onUserInteractionFinished instead of .onTextChanged like displayed in image underneath:
After that I wrote this javascript code:
(function (TcHmi) {
var CheckTextboxForNumber = function (Textbox) {
//get content from the textbox
var _text = Textbox.getText();
//convert to time variable in
if (!_text.startsWith('PT')) {
var _value = Number(_text);
Textbox.setText('PT' + _value.toFixed(3) + 'S');
return _value.toFixed(3);
}
};
TcHmi.Functions.registerFunction('CheckTextboxForNumber', CheckTextboxForNumber);
})(TcHmi);
I put the code in before the Write To Symbol, with an added rounding, because the rounding is done differently after the 3th decimal: when I tested it without rounding the decimals, starting with the 4th, the PLC would display other decimals then I input in the HMI textbox.
What I input in the 'actions and conditons' window can be seen in below image:
After that it worked as it was supposed to.
Try the object "Numeric input" on the TC Hmi to write variable in the PLC, with the event ".onUserInteractionFinished". it should work.

I wish to have a list of text items in a PySimpleGUI that I can update later. That is, I want to have a key for the list. This might be vertical or horizontal, and I do not know how many items there will be.
I end up with different use cases, but the current one is to make a single line of text items with different colors. Other times, I need to write and update a customized table, just different enough that the table widget does not work.
Conceptually, I want to do something like this:
layout = [ [sg.T('Titles and Things')], sg.ListThing(key='-data-', [[]]) ]
so that I can:
window['-data-'].update(values=[ [sg.T(v, color=c)] for (v,c) in my_data ])
Another, invalid syntax, way of saying what I want is to use [key="-data-", sg.T('Item1'), sg.T('Item2')].
Is this possible?
You can update individual layout elements but you cannot dynamically change the layout itself.
It is possible to create 2 or more elements, whereby only one of them is visible, and switch them later as needed. Or you can close and re-create the window with another layout. Or combine both approaches.
An example of switching layouts:
def change_layout():
left_col_1 = sg.Column([[sg.Text(f'Text {i}') for i in range(4)]], visible=True, key='col_1')
left_col_2 = sg.Column([[sg.Text(f'Text {i}')] for i in range(6)], visible=False, key='col_2')
visible_1 = True
layout = [[sg.Column([[left_col_1, left_col_2]]), sg.Button('Change layout', key='change')]]
window = sg.Window('window', layout=layout, finalize=True)
while True:
event, values = window.read()
print(event)
print(values)
print(visible_1)
if event in ('Exit', sg.WIN_CLOSED):
break
if event == 'change':
window['col_1'].update(visible=not visible_1)
window['col_2'].update(visible=visible_1)
visible_1 = not visible_1
Please notice that the alternative layouts for the left part (left_col_1, left_col_2) need to be enclosed in a container (column, frame) to keep their position in the window in the moment they are invisible.
This is how I add my player's texture/image:
Player = SKSpriteNode(imageNamed:"player8")
How do I change the players texture/image without adding or deleting spritenodes?
You assign a different texture:
player = SKSpriteNode(imageNamed:"player8")
Sometime later:
player.texture = SKTexture(imageNamed:"player123")
Hint: it is bad style to begin variable, property and method names with an uppercase character as it makes them appear to be classes.
I have a GTK# TextView and I want to read the line of text under the cursor. I don't see a single method that will do that, so I think I need to combine several method calls, like Buffer.GetText, Buffer.GetIterAtOffset, Buffer.CursorPosition, but it's not obvious to me what the right combination is.
TextIter are a bit odd to use. Buffer.CursorPosition gives you the current position.
It's easy to find the end of the line:
var end = Buffer.CursorPosition;
end.ForwardToLineEnd();
To get the first character, there's not symetrical method, so you might try:
var start = Buffer.CursorPosition;
start.BackwardChars(start.LineOffset); // LineOffset gives you the iter offset on the current line.
sorry for my question and for the long explanation following here, probably there's a simple solution for someone who is experienced in Cocoa and Objective-C, but I'm just starting few weeks ago and I can't figure out how to get this thing working, Grrrrrrr!!
OK, let's put it like this, in my window I have the following:
2 TextField(NSTextField) called:
blockOffText
blockOnText
1 Label(NSTextField) called:
flightTimeText
1 button(NSButton) called:
updateButton
What I want to do is all about time calculation I guess, get the "start-time" in one TextField and the "end-time" in the other.
One is supposed to be the "takeoff-time" and the other the "landing-time" or for example the "duty-startTime" and "duty-endTime"...it's the same!
Then I want to calculate the "flight-time" or "duty-time" and show it in the Label.
At the end I will also need to store the value or the time in a database as an integer, the value should be represented by all minutes corresponding to each time, but the database part is not a problem at the moment.
Maybe I can write the number in the TextField without the format but just the number and get the time show-up formatted in some way?
I would like to write for example "1245" and "1525" without having the needs to put the ":" between the hours and minutes, then can I get the value formatted "12:45" "15:25" in the TextField in some way? Maybe after pressing the button?
Ok, that is a second problem anyway, my real problem is I need to get the value I wrote in the TextField ("1245" and "1525") to be assigned to some variables in the program that I called "BlockOff" and "BlockOn".
I need to transform them in an integer that represent the minutes corresponding to their value..example:
The 1245 will become 765 minutes...(12 times 60 + 45)
and 1525 will become 925 minutes...(15 times 60 + 25)
HOW CAN I DO THIS?
In this way I can use the minutes to calculate the difference to get the flight time or even add flight time to other flight time.
At the moment my program works a little bit differently... like this:
If I directly assign the value to the two variables:
int blockOff = 765;
int blockOn = 925;
then I can calculate and show in the two TextField the takeOff and landing time formatted like I want: "12:45" "15:25"...I use other 2 variables to do so:
int oreBlkOff, minBlkOff = 0;
minBlkOff = blockOff % 60;
oreBlkOff = (blockOff - minBlkOff) / 60;
Then I can show the value in the TextField:
[blockOffText setStringValue:[NSString stringWithFormat: #"%d:%d", oreBlkOff, minBlkOff]];
Same with blockOnText and flightTimeText, so there is no problem there, but this is not really what I need right?
HOW CAN I GET THE VALUE OF THE TEXTFIELD AND STORE THE VALUE IN VARIABLES THAT CAN BE USED TO DO CALCULATION?
HOW DO I GET THE FIRST TO DIGITS AND LAST TO DIGITS FROM THE VARIABLES SO I CAN USE THEM AS HOURS AND MINUTES FOR MY CALCULATION?
I WOULD LIKE TO BE ABLE TO TYPE THE VALUE IN THE TEXTFIELD, PRESS "ENTER" OR "RETURN" AND GET THE VALUE ASSIGNED IN THE VARIABLE.
IS THIS THE CORRECT WAY OR I'M JUST GOING THE WRONG WAY IN THIS.
IN ANOTHER PROGRAM I DID IN VISUAL BASIC THAT WAS THE WAY I USED.
THANK YOU VERY MUCH IN ADVANCE FOR YOU HELP!

To get the int value from text field you'd use integerValue or floatValue for float. But you should definitely check out the date/time controls in cocoa.
Ok, if I didn't miss the point of your long question...
You have a text field with something like #"2345:8743" and you want to get the two numbers in int variables (a=2345, b=8743).
First you need to get these two text representations of your numbers in two NSStrings. You can do it like this:
NSString * yourString = #"2345:8743";
NSString *stringA = [yourString substringToIndex:4]; //stringA = #"2345"
NSString *stringB = [yourString substringFromIndex:5]; //stringB = #"8743";
Now to get the in values, just do:
int a = [stringA intValue];
int b = [stringB intValue];
Let me know if that is helpful to you.
