Grid Uniform Configuration
Here we would like to have some left, right, top and bottom margins
We could set the size of the margins individually, but it would be comfortable, if the size of the margins could be changed at once for all margins
Therefore the entry 'uniform' exists
We just give a grid configuration a name by an entry in uniform. Let's see, whether there was some change
The individual options show, that the columns can't be changed now by changing the entries for the general column configuration. These entries would now change columns with uniform 'margin'. But we still don't have such ones jet.
And indeed changing the minsize to 80 didn't have any effect
Also comfortable is, that the insert mode takes uniform entries into account
The new inserted columns have got a size of 80. The red border of the canvasses shows, that these columns have uniform values. And the color of these canvasses is the same color as the color of the entry field with 'margin'.
This should mean, that we could change the size of the margins by such an entry
Yes indeed
Maybe we should use the same margin values also for bottom and top?
After typing 'margin' here in the green uniform entry field, the row values automatically changed to the values for the columns
After inserting the margin for top and bottom, the canvasses show the green color of the uniform entry field for the rows
After erasing 'margin' from the column uniform entry field, the column values changed to the general grid column values and the canvasses for the colummns with uniform values 'margin' became green, because these columns may still be changed via the grid layout gui, by changing the entries for the rows.
Row or column with uniform have only the meaning, that this will be used for inserting rows or columns. But changing values applies to all rows or columns with the same uniform values.
Changing the minsize entry for the row to 6 affected also the columns, because this isn't now the entry for rows, but for the uniform 'margin'.
After erasing also the uniform entry for the rows whole the grid layout gui changed back to the general grid configuration
How to change the uniform values
Changing may be done by all means of changing individual rows or columns.
by grid bars
by mouse wheel or these Toplevel guis, which you get by right mouse button click on a canvas at the right or bottom side
Interesting is here also the button 'Abc'
It transfers the uniform entry to the uniform entry field for row or column in the grid layout gui
Just change one uniform configuration and all other rows or columns with the same uniform will change
Please note:
This isn't the original tkinter behaviour. In tkinter only the first defined uniform setting counts. For other row or columns with the same uniform value, their own minsize, pad and weight values don't matter.
The GuiDesigner doesn't remember the uniform master, but just changes all.
