With many hours of testing, I did have success in running two Tk() loops, but it had potential to be problematic, as "Bryan Oakley" had posted in many threads about.

Ultimately, I decided when I was in need of running something alone, I'd start my GUI with arguments and process it in an entirely new process instead of passing any arguments directly. Seems like a safer option.

If you want to stick to using a Plain button, try entering a thin space (U+2009) character as the title, which won't consume much space and solves the issue. (Thanks to @El Tomato for suggesting white space characters)

Change color of child button element regardless of box decoration background color

Asked 2022-Mar-03 at 11:56

I am building a landing page that has a logo and then a sign in and login button below it. I used a box decoration to specify the background color because I am very particular about the gradient scheme. However, I realize it may have some kind of "absolute" effect on my container widget because I can't seem to change the colors of the buttons within the widget. I am new to flutter UI and I am probably layering the widgets incorrectly, but any help would be greatly appreciated! Here's the code for the landing page:

ANSWER

Answered 2022-Feb-27 at 16:17

I do believe you just want to add a second NSWindow, or a NSPanel. Without a child window relation. In AppKit document-based apps you would for example overwrite -[NSDocument makeWindowControllers] and setup multiple window controllers for one document.

Child windows are for special use cases, for example: functionality like autocompletions lists, where you would want a chrome-less window with a table view beneath a textfield, which automatically follows the parent window when moved.

Here is TextEdit with such a autocompletions window and the Xcode Debug View Hierarchy of the same:

See this note from the documentation:

After the childWin is added as a child of the window, it is maintained in relative position indicated by place for subsequent ordering operations involving either window. While this attachment is active, moving childWin will not cause the window to move (as in sliding a drawer in or out), but moving the window will cause childWin to move.

I don't believe that a child window was ever intended to be independently moved from its parent window, especially different screens.

How to open a new MDI sub-window in PyQt5?

Asked 2022-Feb-14 at 18:51

What I want to do is to open a new Countrypage sub-window by clicking on the "New" button which is in Countrypage itself.

For example, if I click the "New" button in a CountryPage window (window title: "Country page"), one more new Countrypage window will be opened in the MDI area (window title: "Country Page 1"). Now if we click the "New" button in "Country Page 1", one more new window will open in the MDI area (window title: "Country page 2") and so on - and I want to close the windows one by one by pressing the corresponding "Close" button in Countrypage. New window are opened only by pressing a "New" button.

And if we close the last opened window by pressing the "Close" button, the text item in the "Country" text-box will be automatically updated in the previous window's "Country" text-box and so on.

Main Script :

ANSWER

Answered 2022-Feb-14 at 18:38

The adding and closing of sub-windows is best handled by the main-window. The CountryPage class doesn't need to know anything about the sub-windows. The new/close buttons can be directly connected to methods of the main-window. This makes it easier to manage the sub-windows via the functions of the mdi-area.

How to dynamically define Headers and Settings for UWP NavigationView's menu, using C++/winRT?

I'm working on a cross-platform project in C++ generating the UI dynamically, and I am struggling with C++/winRT UWP NavigationView on two problems:

When defining a NavigationViewItemHeader, the resulting header title doesn't show in the navigation menu, the space remains empty,
When trying to update the SettingsItem of the navigation menu, the value of the Settings navigation item is nullptr as returned by SettingsItem().

Dynamic Headers/Footers enable different grouping options in reports, such as "By Location" or "By Location By System": Note that the words "Report Definitions" are circled above. Although reports can have up to three Dynamic Headers/Footers, some reports only have one or two Dynamic Groups.

This kind of cases is exactly what VisualTransformation is intended for.

Here's a Googler's comment on another issue:

I don't think we can fix this issue easily.

The filtering text in onValueChanged callback is generally not recommended because the text state is shared with out process IME(software keyboard). The filtering text means the text content changes internally, then the new state is notified to IME. This is not a normal path to IME and different IME reacts differently to this unexpected state change. Some IME may try to reconstruct the composition, others may give up and start new session, etc. This is mostly due of the historical reason and hard to fix from now. So, please avoid filtering text in onValueChanged callback and consider following alternatives:

(Recommended) Don't filter it and show error message. (irrelevant here)

Use VisualTransformation for changing visual output without modifying edit buffer.

QUESTION

Achieve Unique Column Width for each Cell in Different Rows with a GridPane?

Asked 2021-Nov-24 at 16:43

I am trying to model credit card data in JavaFx using a GridPane:

My model contains 3 rows (Note: each field is comprised of label + text field):

Row 1: First name and last name (4 fields)

Row 2: Credit card number (2 fields)

Row 3: Expiration date - month, year + CVV (6 fields)

See screenshot below:

I was reading this tutorial which states:

All cells in the same row will have the same height, and all cells in the same column will have the same width. Different rows can have different heights and different columns can have different widths.

Are there any workarounds to to have different size columns on a row by row basis in a GridPane?
