Troubleshooting

These items may solve your problem. Please check those you've done by changing - [ ] to - [X]

• [x ] Searched main docs for your problem www.PySimpleGUI.org
• Looked for Demo Programs that are similar to your goal. It is recommend you use the Demo Browser! Demos.PySimpleGUI.org
• If not tkinter - looked for Demo Programs for specific port
• For non tkinter - Looked at readme for your specific port if not PySimpleGUI (Qt, WX, Remi)
• [x ] Run your program outside of your debugger (from a command line)
• [x ] Searched through Issues (open and closed) to see if already reported Issues.PySimpleGUI.org
• [x ] Have upgraded to the latest release of PySimpleGUI on PyPI (lastest official version)
• [x ] Tried using the PySimpleGUI.py file on GitHub. Your problem may have already been fixed but not released

Detailed Description

Without expanding X on any:

    tab2_layout = [
        [sg.Text("Current chat: None", key="-current_chat-")],
        [sg.Text("Chats:")],
        [sg.Table(values=[], headings=["Name:", "Last Message:", "Timestamp:"], key="-table_chats-", enable_events=True, expand_y=True), sg.Listbox(values=("1", "2", "3"), select_mode=sg.LISTBOX_SELECT_MODE_SINGLE, expand_y=True, key="-listbox_chats-")],
        ]

When I add expand_x=True to only the second element (Listbox), they both shift, which is not what I think is intended?:

Code To Duplicate

A short program that isolates and demonstrates the problem (Do not paste your massive program, but instead 10-20 lines that clearly show the problem)

This pre-formatted code block is all set for you to paste in your bit of code:

   tab2_layout = [
        [sg.Text("Current chat: None", key="-current_chat-")],
        [sg.Text("Chats:")],
        [sg.Table(values=[], headings=["Name:", "Last Message:", "Timestamp:"], key="-table_chats-", enable_events=True, expand_y=True), sg.Listbox(values=("1", "2", "3"), select_mode=sg.LISTBOX_SELECT_MODE_SINGLE, expand_y=True, expand_x=True, key="-listbox_chats-")],
        ]

Sorry if I'm just using it wrong, but from what I've seen it looks like it should work?

Intended Sketch:

There's bug not yet fixed if you use different setting of expand_x or expand_y for different elements in the same row.

Demo Script

import PySimpleGUI as sg


def repack(widget, option):
    pack_info = widget.pack_info()
    pack_info.update(option)
    widget.pack(**pack_info)

layout = [
    [sg.Text("Current chat: None", key="-current_chat-")],
    [sg.Text("Chats:")],
    [sg.Table(values=[], headings=["Name:", "Last Message:", "Timestamp:"], key="-table_chats-", enable_events=True, expand_x=True, expand_y=True),
     sg.Listbox(values=("1", "2", "3"), select_mode=sg.LISTBOX_SELECT_MODE_SINGLE, expand_x=True, expand_y=True, key="-listbox_chats-")],
]
window = sg.Window('Title', layout, size=(640, 480), finalize=True)

repack(window["-table_chats-"].widget, {'fill':'y', 'expand':0})

# repack required also for the element frame for some elements with `element_frame`, like sg.Table, sg.Listbox, ...
repack(window["-table_chats-"].element_frame, {'fill':'y', 'expand':0, 'before':window["-listbox_chats-"].element_frame})

window.read(close=True)

Ah, thank you.

import PySimpleGUI as sg
defaul = [

right have expand_y works but expand x not work

There's one invisible container for elements when layout.

The left element decide the height of the container, so the height of the right one expanded to the height of the container.

The width of the container is the sum of width of the left element and right element, so the width of the right element expand do nothing.

bottom have expand_x work but expand_y not

The same, the width of container is wider than the width of the bottom element, so the width of the bottom element expanded.

The height of the container is the sum of the height of the left and botton elements, so the height of bottom element expand do nothing.

The expand_x option do nothing for the widths of elements at the same row, the same, the expand_y option do nothing for the heights of elements at different rows.

Here, the left and right elements are in the same row, so expand_x do nothing. Again, the Left/right elements and the bottom element are in different rows, so expand_y do nothing.

ı change window size

just add expand_x

ı remove y size left and give right expand_y

bottom size bigger thans left and right only ı use expand_x and expand_y

expand and expand y looks work fit empty space

[jason990420]

It looks fine !

[gnuchanos]

ı'm not say something wrong ı just show how works expand simple way
