styling

问题 I want to set the Style for my elements in qml. For that, I want to use a style like Material Style.

问题 I have a GtkEntry that's I'd like to allow users to style with their choice of font (or system default). I end up with a Pango description string like "Monospace 10" to describe the font. I'm currently using override_font , which is deprecated in favour of CSS styling.

问题 Per this example the to_excel method should save the Excel file with background color. However, my saved Excel file does not have any color in it. I tried to write using both openpyxl and xlsxwriter engines. In both cases, the Excel file was saved, but the cell color/style was lost. I can read the file back and reformat with openpyxl , but if this to_excel method is supposed to work, why doesn't it? Here is the sample code. import pandas as pd # version 0.24.2 dict = {'A': [1, 1, 1, 1, 1], 'B

问题 For a pandas data frame of: I want to reformat it to: However, the styling is lost. How can I retain the styling whilst reformatting? Instead, formatting after the fact would also be fine. But parsing the string to numbers to validate styling conditions seems complicated as the number of digits is not constant. It was constructed by: import pandas as pd import numpy as np df_source = pd.DataFrame({'foo': [['0.001', '0.001', '0.190'], ['0.220', '0.029', '0.000'], ['-0.754', '0.202', '0.000'],
