Hi I am a very novice when it comes to scripting. I am trying to write a Jython script that will take an image that is not at the front, in imageJ, and bring it to the front. I have tried using the WindowManager but routinely run into a similar error.
TypeError: setCurrentWindow(): 1st arg can't be coerced to
ij.gui.ImageWindow
or some other form of this error. It seems as though activating an image that is not at the front shouldn't be too difficult.
Here is the code I'm using:
from ij import IJ
from ij import WindowManager as WM
titles = WM.getIDList()
WM.setCurrentWindow(titles[:1])
The WindowManager.setCurrentWindow method takes an ImageWindow object, not an int image ID. But you can look up the ImageWindow for a given ID as follows:
WM.getImage(imageID).getWindow()
Here is a working version of your code:
from ij import IJ
from ij import WindowManager as WM
print("[BEFORE] Active image is: " + IJ.getImage().toString())
ids = WM.getIDList()
win = WM.getImage(ids[-1]).getWindow()
WM.setCurrentWindow(win)
win.toFront()
print("[AFTER] Active image is: " + IJ.getImage().toString())
Notes
I renamed your titles variable to ids because the method WindowManager.getIDList() returns a list of int image IDs, not a list of String image titles.
The WM.getImage(int imageID) method needs an int, not a list. So I used ids[-1], which is the last element of the ids list, not ids[:1], which is a subarray. Of course, you could pass whichever image ID you wish.
I added the call win.toFront(), which actually brings the window to the front. Calling WM.setCurrentWindow(win) is important in that it tells ImageJ that that image is now the active image... but it will not actually raise the window, which is what it seems like you want here.

I am using PyQt based on Qt4. My Editor is PyCharm 2017.3 and my python version is 3.4. I am scraping some text from a website. I am trying to align that text to the center of the cell in a QTableWidget.
item = QTableWidgetItem(scraped_age).setTextAlignment(Qt.AlignHCenter)
self.tableWidget.setItem(x, 2,item)
Therefore while putting the item in the cell, I am trying to align it as per the documentation. The problem is that the data is not showing up.
It did show up when I removed setTextAlignment method as shown below
item = QTableWidgetItem(scraped_age)
self.tableWidget.setItem(x, 2,item)
This line of code:
item = QTableWidgetItem(scraped_age).setTextAlignment(Qt.AlignHCenter)
will not work properly, because it throws away the item it creates before assigning it to the variable. The variable will in fact be set to None, which is the return value of setTextAlignment(). Instead, you must do this:
item = QTableWidgetItem(scraped_age) # create the item
item.setTextAlignment(Qt.AlignHCenter) # change the alignment
This didn't work for me, and I'm not sure if it is because I'm using PyQt5 or it i did something wrong. I was trying to find something similar but for the whole table, and i finally stumbled upon something that worked and lets you center every cells or just one column at a time.
You have to use the delegate method:
#You're probably importing QtWidgets to work with the table
#but you'll also need QtCore for the delegate class
from PyQt5 import QtCore, QtWidgets
class AlignDelegate(QtWidgets.QStyledItemDelegate):
def initStyleOption(self, option, index):
super(AlignDelegate, self).initStyleOption(option, index)
option.displayAlignment = QtCore.Qt.AlignCenter
After implementing this in your code, you can add the following to your main window class or wherever the table is defined:
delegate = AlignDelegate(self.tableWidget)
self.tableWidget.setItemDelegateForColumn(2, delegate) #You can repeat this line or
#use a simple iteration / loop
#to align multiple columns
#If you want to do it for all columns:
#self.tableWidget.setItemDelegate(delegate)
Know this is an old question, but hope it can help someone else.
Bit late to the party but for those of you wondering how to do this on pyqt5
table = QTableWidgetItem() #QTWidgets.QTableWidgetItem() if importing QWidget from PyQt5
table.setTextAlignment(number)
setTextAlignment takes an int for the argument (alignment). Put the number in to get the result:
0:left
1:left
2:right
3:right
4:centre
In After Effects scripts, if you want your script to be able to be docked in the program's workspace, the only way to do it as far as I know is to use a resource string like this:
var res = "Group{orientation:'column', alignment:['fill', 'fill'], alignChildren:['fill', 'fill'],\
group1: Group{orientation:'column', alignment:['fill', ''], alignChildren:['fill', ''],\
button1: Button{text: 'Button'},\
},\
}";
myPanel.grp = myPanel.add(res);
The above code creates a script UI with one button ("button1") inside a group ("group1").
I would like to know other ways to create the same resource string. Is it possible to make it using a JSON object and then stringifying it??
I know it can be done somehow, because I have inspected the Duik Bassel script that is dockable and, for example, adds elements like this:
var button1 = myPal.add( 'button' );
but I cannot understand how to do it myself.
TL;DR: I want to make a dockable scriptUI without writing a giant string all at once, but bit by bit, like a floating script.
UI container elements have an add() method which allows you to add other UI elements to them, and you can treat them as normal objects.
var grp = myPanel.add("group");
grp.orientation = "column";
grp.alignment = ['fill', 'fill'];
grp.alignChildren = ['fill', 'fill'];
var group1 = grp.add("group");
…
var button1 = group1.add("button");
button1.text = 'Button'
More details and examples here: https://extendscript.docsforadobe.dev/user-interface-tools/types-of-controls.html#containers
Also worth checking out https://scriptui.joonas.me/ which is a visual scriptUI interface builder. You have to do some work on the code it produces to get panels for AE, but it's not hard.
extendscript still uses a 20th century version of javaScript, which doesn't have JSON built-in, but I have successfully used a JSON polyfill with it.
I used json2.js to get structured data in and out of Illustrator, and it worked beautifully, but I can see there's now a json3.js which might be better for whatever reason. This stackoverflow question addresses the differences.
To load another .js file (such as a polyfill) into your script, you need to do something like
var scriptsFolder = (new File($.fileName)).parent; // hacky but effective
$.evalFile(scriptsFolder + "/lib/json2.js"); // load JSON polyfill
These file locations may differ in other Adobe apps. Not sure what it would be in AfterEffects. I seem to remember that InDesign has a different location for scripts. You can also hardcode the path, of course.
Good luck!
I am trying to make a GUI using PyQt5.
I have a couple of buttons say 4 which call the same function. A click on a button calls the same function to plot the data associated with each button.
radiobutton1.clicked.connect(self.fun)
radiobutton2.clicked.connect(self.fun)
radiobutton3.clicked.connect(self.fun)
radiobutton4.clicked.connect(self.fun)
Since each line of code is the same except the name of the button, is there a way instead of writing almost the same code four times, I use a for loop to generate the code?
You should initialize them in a loop, then append all of the objects to a list. Then, in this case, all you'd have to do is iterate over the list and call the .clicked.connect() method on each object.
radio_buttons = list()
for i in range(1, 5):
temp_radio_button = QRadioButton("Radio Button")
radio_buttons.append(temp_radio_button)
....
for radio_button in radio_buttons:
radio_button.clicked.connect(self.fun)
I know it does not apply to this case, but for those who use QtDesigner and need to access the widgets later, this can be an option:
def get_all_objects(self,label,window,widget_class):
for widget in filter(lambda entry: match(label,entry.objectName()),window.findChildren(widget_class)):
yield widget
for widget in self.get_all_objects('radiobutton',MainWindow,QtWidgets.QRadioButton):
widget.clicked.connect(self.fun)
Note:MainWindow can be replaced by a page on a StackedWidget if all your target widgets are in the same page.
Is there a manner in which one can convert the spectrum type, for instance to EELS, by DM scripting? This screenshot represents what I'm referring to. I'd like to import a dataset using the GMS 3.4 Python interface, and then turn that into a EELS dataset for further processing (ideally without having to manually interface with the screenshotted menu bar).
Yes there is.
The "type" is simply a meta-data tag
which you can easily set with the TagGroup commands.
There is, however, one complication:
Data "registers" itself with DM when it first appears. Changing the meta-tags manually doesn't change this registration. (The menu command, however, does.)
Thus, you will only see effect of the type change when
either:
You save, close and reopen the data
You clone the data, throw away the original, and display the clone
The second option might cause issues with data-linkage though, as the unique image ID of the data is newly created.
Example using the first method (requires save & load):
image img:=GetFrontImage()
TagGroup tg = img.ImageGetTagGroup()
tg.TagGroupSetTagAsString("Meta Data:Signal","EELS")
imageDocument doc = img.ImageGetOrCreateImageDocument()
doc.ImageDocumentSave(0)
string path = doc.ImageDocumentGetCurrentFile()
doc.ImageDocumentClose(0)
doc = NewImageDocumentFromFile(path)
doc.ImageDocumentShow()
An alternative option is to rely on the menu command. If it is present, then you can simply use the ChoseMenuItem() command to invoke it.
However, the command will only be available with the UI when the data you want to change is front-most (i.e. not a script window!) You will need to ensure by script, that this is the case. A simple ShowWindow() will do.
image img:=GetFrontImage()
img.ShowImage()
if ( !ChooseMenuItem("Spectrum","Convert Data To","None") )
Throw( "Conversion to none failed.")
if ( !ChooseMenuItem("Spectrum","Convert Data To","EDS") )
Throw( "Conversion to none failed.")
Disadvantage of this solution: You will get the user-prompts.
I'm trying to check if a value is contained in the innertext of a webelement but I'm having a little problem: frames seem to change at every refresh of the pages.
These are the steps I've recorded:
Browser("SystemPage").Page("SystemP").Frame("dme2_header").Image("Gestione Anagrafiche").Click<br>
Browser("SystemPage").Page("SystemP").Frame("dme2_appl").WebEdit("pdrBean.pdrPod").Set parameter("POD")<br>
Browser("SystemPage").Page("SystemP").Frame("dme2_appl").WebButton("Cerca").Click
Browser("SystemPage").Page("SystemP").Frame("dme2_appl_2").Image("show_files").Click
Browser("SystemPage").Page("SystemP").Frame("dme2_appl_6").Image("Lente").Click
cctype = Browser("SystemPage").Page("SystemP").Frame("dme2_appl_7").WebElement("arrow_down").GetROProperty("innertext")<br>
DataAct = Browser("SystemPage").Page("SystemP").Frame("dme2_appl_7").WebElement("arrow_down_2").GetROProperty("innertext")<br>
Browser("SystemPage").Page("SystemP").Frame("dme2_header").Image("Gestione Anagrafiche").Click
The frames "dme2_appl6" and "dme2_appl7" changes at every refresh of the two pages.
The question is simple: how can I rewrite these two actions to make them universal?
I've tried to do something like:
Set objFrame = Frame("title:=dme2_appl_.")
and then
Browser("SystemPage").Page("SystemP").objFrame.Image("Lente").Click
But QTP gives me an error in return: "property or method not supported by the object"
Please try using the below code
Browser("SystemPage").Page("SystemP").Image("Lente").Click
Avoid using the "Frame" and if you really want to use it, put regex for name property of Frame.
Go to Object Properties--> Click on the Frame object --> Mandatory Properties--> Change name property as
like iFrame_213123123 to i.*
Hope this will solve your problem.
I don't think you can use a frame object that way. When you write Page().Frame() UFT sets the frame's parent in different way than if you first create the Frame.
Think of Frame() as a function that behaves differently when called on a Page or as a free function.
Try:
Browser("SystemPage").Page("SystemP").Frame("title:=dme2_appl_.")
