Adding QTableWidget and QLabel with Pixmap side by side using PyQt6
I am trying to build a GUI with PyQt6 in python where I create a table and an image to the right inside a tab.
For some reason it creates the table occupying the entire screen and does not show the QLabel (for now I am using text as a placeholder).
def set_tab_info(self, num_rows): # Sets the structure for each tab
self.num_rows = num_rows
tab_info = [
{"name": "Junction", "columns": 11, "header_labels": ["Type", "X", "Shear Plane Location", "Fastener Position", "Bolt/Screw", "Under head", "Thread",
"Minimum friction coefficient under bolt head", "Maximum friction coefficient under bolt head",
"Minimum friction coefficient on thread", "Maximum friction coefficient on thread"],

self.create_tabs(tab_info)
def create_tabs(self, tab_info): # Creates each tab by receiving the structure from the set_tab_info method
self.column_inputs = {}
for info in tab_info:
tab_widget = QWidget()
tab_layout = QGridLayout(tab_widget)
horizontal_layout = QGridLayout()
table = QTableWidget(self.num_rows, info["columns"])
table.setHorizontalHeaderLabels(info["header_labels"])
for row in range(self.num_rows):
for col in range(info["columns"]):
if info["editor_types"][col] == "line_edit":
item = QLineEdit()
table.setCellWidget(row, col, item)
self.column_inputs[(info["name"], info["header_labels"][col])] = item
elif info["editor_types"][col] == "combo_box":
item = QComboBox()
item.addItems(self.get_combo_box_items(info["header_labels"][col]))
table.setCellWidget(row, col, item)
self.column_inputs[(info["name"], info["header_labels"][col])] = item
else:
item = QTableWidgetItem()
table.setItem(row, col, QTableWidgetItem())
table.resizeColumnsToContents()
image_label = QLabel("Placeholder")
horizontal_layout.addWidget(table, 0, 0, 1, 2)
horizontal_layout.addWidget(image_label, 0, 1, 1, 1)
tab_layout.addLayout(horizontal_layout, 1, 0, 1, 3)
self.tabs.addTab(table, info["name"])
I have made some research and tried asking for some help to ChatGPT I have not been able to find any reason for why it is not displaying the QLabel. Find an image below of how it is looking now.
If possible I would like the table to occupy 2/3 of the screen horizontally and the image the remaining 1/3
Solution
Try it:
class MainWindow(QWidget):
def __init__(self):
super().__init__()
self.tabs = QTabWidget()
self.grid = QGridLayout(self)
self.grid.addWidget(self.tabs)
num_rows = 0
self.set_tab_info(num_rows)
def set_tab_info(self, num_rows): # Sets the structure for each tab
self.num_rows = num_rows
tab_info = [
