I am trying to add information to my Listbox and keeping it the size I state when I configure it. Here is my code for the Listbox with the scrollbar and an image of what it looks like.
Picture of the listbox.
taskList = Listbox(setBox, bg="#1B2834",fg="white")
taskList.configure(width=183,height=39)
taskList.pack(side=LEFT,fill=BOTH)
taskScroll = Scrollbar(setBox)
taskScroll.configure(bg="#1B2834",width=18)
taskScroll.pack(side = RIGHT, fill = BOTH)
taskList.config(yscrollcommand = taskScroll.set)
taskScroll.config(command = taskList.yview)
Now, when i click a button the command is to execute this following code:
def savetasks():
#make tasks
letters = string.ascii_uppercase
result_str = ''.join(random.choice(letters) for i in range(4))
num = str(random.randrange(0,9))
taskIDnum = num+result_str
taskIDLBL = Label(taskList, text=taskIDnum,bg="#1B2834", fg="White")
taskIDLBL.configure(padx=20,pady=10)
taskIDLBL.pack()
This code works fine as well, creating new labels with a random ID but it resizes the listbox to look like this...
Picture of the list box after clicking the button to execute the command.
Lastly, the scroll bar is not scrollable and when I create a lot of id's that end up going off my screen I cannot use the scroll bar to scroll down to see them, is there a way to not let the Listbox be resized and is it possible to set the Listbox with max and min-height?
If there is an easier way to do this without using a Listbox please let know, I just need to able to scroll down to see all the other id's and I didn't see any other way to use a scroll bar, that I NEEDED to use a Listbox
Disclaimer: I have only begun to learn about Python. I took a crash course just to learn the very basics about a month ago and the rest of my efforts to learn have all been research thru Google and looking at solutions here in Stack Overflow.
I am trying to create an application that will read all PDF files stored in a folder and extract their filenames, page numbers, and the contents of the first page, and store this information into a 2D set. Once this is done, the application will create a tkinter GUI with 2 listboxes and 1 text box.
The application should display the PDF filenames in the first listbox, and the corresponding page numbers of each file in the second listbox. Both listboxes are synched in scrolling.
The text box should display the text contents on the first page of the PDF.
What I want to happen is that each time I click a PDF filename in the first listbox with the mouse or with up or down arrow keys, the application should display the contents of the first page of the selected file in the text box.
This is how my GUI looks and how it should function
https://i.stack.imgur.com/xrkvo.jpg
I have been successful in all other requirements so far except the part where when I select a filename in the first listbox, the contents of the first page of the PDF should be displayed in the text box.
Here is my code for populating the listboxes and text box. The contents of my 2D set pdfFiles is [['PDF1 filename', 'PDF1 total pages', 'PDF1 text content of first page'], ['PDF2 filename', 'PDF2 total pages', 'PDF2 text content of first page'], ... etc.
===========Setting the Listboxes and Textbox=========
scrollbar = Scrollbar(list_2)
scrollbar.pack(side=RIGHT, fill=Y)
list_1.config(yscrollcommand=scrollbar.set)
list_1.bind("<MouseWheel>", scrolllistbox2)
list_2.config(yscrollcommand=scrollbar.set)
list_2.bind("<MouseWheel>", scrolllistbox1)
txt_3 = tk.Text(my_window, font='Arial 10', wrap=WORD)
txt_3.place(relx=0.5, rely=0.12, relwidth=0.472, relheight=0.86)
scrollbar = Scrollbar(txt_3)
scrollbar.pack(side=RIGHT, fill=Y)
list_1.bind("<<ListboxSelect>>", CurSelect)
============Populating the Listboxes with the content of the 2D Set===
i = 0
while i < count:
list_1.insert(tk.END, pdfFiles[i][0])
list_2.insert(tk.END, pdfFiles[i][1])
i = i + 1
============Here is my code for CurSelect function========
def CurSelect(evt):
values = [list_1.get(idx) for idx in list_1.curselection()]
print(", ".join(values)) ????
========================
The print command above is just my test command to show that I have successfully extracted the selected item in the listbox. What I need now is to somehow link that information to its corresponding page content in my 2D list and display it in the text box.
Something like:
1) select the filename in the listbox
2) link the selected filename to the filenames stored in the pdfFilename 2D set
3) once filename is found, identify the corresponding text of the first page
4) display the text of the first page of the selected file in the text box
I hope I am making sense. Please help.
You don't need much to finish it. You just need some small things:
1. Get the selected item of your listbox:
selected_indexes = list_1.curselection()
first_selected = selected_indexes[0] # it's possible to select multiple items
2. Get the corresponding PDF text:
pdf_text = pdfFiles[first_selected][2]
3. Change the text of your Text widget: (from https://stackoverflow.com/a/20908371/8733066)
txt_3.delete("1.0", tk.END)
txt_3.insert(tk.END, pdf_text)
so replace your CurSelect(evt) method with this:
def CurSelect(evt):
selected_indexes = list_1.curselection()
first_selected = selected_indexes[0]
pdf_text = pdfFiles[first_selected][2]
txt_3.delete("1.0", tk.END)
txt_3.insert(tk.END, pdf_text)
I am trying to add icons next to text in a listview, but I keep getting an error saying I need to imagelist must be initialised before it can be used.
On the form window as it loads, I have the following code:
Private Sub UserForm_Initialize()
ImageList3.ListImages.Add Key:="Koala", Picture:=LoadPicture("\images\add_icon.gif")
end sub
Then I am trying to populate the listview like this
li.ListSubItems.Add , , "Test", "Koala"
What am I doing wrong?
You need to link your ImageList to the ListView using the Icons-property. Add the following line in the UserForm_Initialize - this must be done before you populate the ListView (of course you need to adapt the name of the ListView)
Me.ListView1.Icons = ImageList3
I want to put a transparent label on top of a sheet in Excel, so that I can take advantage of the MouseMove event of the label to "draw cells" (aka change their fill color and so on) by mouse click / drag / etc. - since I can't do that on the cells per se.
Now everything works just fine, except that I can't make the label transparent at runtime (aka in VBA) ... while by doing exactly the same thing in Design Mode works as expected. Specifically, I have the code (more or less):
Dim MapLabel As OLEObject
On Error Resume Next
Sheet2.OLEObjects("MapLabel").Delete
Set MapLabel = Sheet2.OLEObjects.Add("Forms.Label.1")
MapLabel.name = "MapLabel"
MapLabel.Placement = xlMoveAndSize
MapLabel.Object.Caption = ""
' Problem line below
MapLabel.Object.BackStyle = fmBackStyleTransparent
' Problem line above
MapLabel.Left = Sheet2.cells(2, 6).Left
MapLabel.Top = Sheet2.cells(2, 6).Top
MapLabel.Width = Sheet2.cells(2,6).Width * 10
MapLabel.Height = Sheet2.cells(2,6).Height * 10
So, in words, I first delete the label named 'MapLabel', then recreate it (the above code goes into a "init" Sub). All the code lines except the one marked produce the desired result. The marked one does set the BackStyle property of the label to fmBackStyleTransparent ... but it doesn't actually make the label transparent. This is frustrating, because it's the same approach that works flawlessly at design time!
Do you have a solution to this? I read about solving similar problems by declaring the label as MsForms.Label or as Control, but the sheet object doesn't have those properties, plus, there are far more label properties which can be set using the OLEObject than with the help of MsForms.Label or Control.
All you need to do after this line:
MapLabel.Object.BackStyle = fmBackStyleTransparent
put this line:
ActiveSheet.Shapes(MapLabel.Name).Fill.Transparency = 1
I hope I helped.
P.S. If you need explanation i will edit my answer.
I had the same problem as you but in Word. The solution for me was to do the following:
In design mode:
Right click on the object
Navigate to Switch to automatic form/Image > Wrapping > In front of the text
Add an empty picture to your label
I developed an RSS Application for two XML files and displayed it on two LWUIT Tabs. The problem is with my LWUIT TextArea, whenever I click on my ListForm (it contains titles from the RssFile), I need to display description information from the RSS File. First time I am able to display the description related to the title clicked in ListForm. If I click the ListForm the next time onwards I am able to display the same description again and again in the textarea..(Eventhough I am getting Related Description from RssFile)
Here is my Code:
private void displayCompleteNewsScreen(News detailNews) {
Label title = new Label(detailNews.getTitle());
form2.setTitleComponent(title);
String Description = detailNews.getDescription();
System.out.println("Description" + Description);//Here i am able to get different Description values Related to myList Screen but in text area it is displaying First one always
big = new TextArea();
big.setEditable(false);
big.setText(Description);
form2.addComponent(pubDate);
form2.addComponent(big);
form2.show();
}
As you are reusing form2 instance you should clear it in displayCompleteNewsScreen method. Call removeAll before calling setTitleComponent.
And don't forget to set form2 Commands again in displayCompleteNewsScreen.
