QUESTION
I am able to use SQLite3
as the database (DB) and get Treeview
to display data from the DB. However, I was wondering whether Treeview
has any functionality to censor the first few characters in a certain column for all entries?
Here is the lean code:

I have three tables: event, speaker, event_speaker
Events and speakers have an n:m relationship managed by the "event_speaker" table. I used the jOOQ maven codegen to generate files like "EventRecord" and "SpeakerRecord".
In my application I want to get all speakers for a particular event. So I need to join the "speaker" table with the "event_speaker" table to be able to limit the results by the event id:

The first time I used XAMPP, I created a folder named E_Shop
and ever since I hit localhost
or 127.0.0.1
in my URL address bar of my browser, I am directed to this E_Shop
folder I created once,
now I have created another folder named PHP_execises
in the same location I created E_Shop
, in the htdocs
folder of XAMPP folder, and I created a PHP file inside PHP_exercises
, and here is the problem as you might guess: In the URL bar of the browser, hitting localhost/PHP_exercises
pops an URL error, and hitting localhost alone, directs me to the E_Shop
folder as default, and not the XAMPP file directories!

QUESTION
I am using a 3.5: TFT LCD display with an Arduino Uno and the library from the manufacturer, the KeDei TFT library. The library came with a bitmap font table that is huge for the small amount of memory of an Arduino Uno so I've been looking for alternatives.
What I am running into is that there doesn't seem to be a standard representation and some of the bitmap font tables I've found work fine and others display as strange doodles and marks or they display upside down or they display with letters flipped. After writing a simple application to display some of the characters, I finally realized that different bitmaps use different character orientations.
My questionWhat are the rules or standards or expected representations for the bit data for bitmap fonts? Why do there seem to be several different text character orientations used with bitmap fonts?
Thoughts about the questionAre these due to different target devices such as a Windows display driver or a Linux display driver versus a bare metal Arduino TFT LCD display driver?
What is the criteria used to determine a particular bitmap font representation as a series of unsigned char values? Are different types of raster devices such as a TFT LCD display and its controller have a different sequence of bits when drawing on the display surface by setting pixel colors?
What other possible bitmap font representations requiring a transformation which my version of the library currently doesn't offer, are there?
Is there some method other than the approach I'm using to determine what transformation is needed? I currently plug the bitmap font table into a test program and print out a set of characters to see how it looks and then fine tune the transformation by testing with the Arduino and the TFT LCD screen.
My experience thus farThe KeDei TFT library came with an a bitmap font table that was defined as
...ANSWER
Answered 2021-Jun-12 at 16:19Raster or bitmap fonts are represented in a number of different ways and there are bitmap font file standards that have been developed for both Linux and Windows. However raw data representation of bitmap fonts in programming language source code seems to vary depending on:
- the memory architecture of the target computer,
- the architecture and communication pathways to the display controller,
- character glyph height and width in pixels and
- the amount of memory for bitmap storage and what measures are taken to make that as small as possible.
A brief overview of bitmap fonts
A generic bitmap is a block of data in which individual bits are used to indicate a state of either on or off. One use of a bitmap is to store image data. Character glyphs can be created and stored as a collection of images, one for each character in the character set, so using a bitmap to encode and store each character image is a natural fit.
Bitmap fonts are bitmaps used to indicate how to display or print characters by turning on or off pixels or printing or not printing dots on a page. See Wikipedia Bitmap fonts
A bitmap font is one that stores each glyph as an array of pixels (that is, a bitmap). It is less commonly known as a raster font or a pixel font. Bitmap fonts are simply collections of raster images of glyphs. For each variant of the font, there is a complete set of glyph images, with each set containing an image for each character. For example, if a font has three sizes, and any combination of bold and italic, then there must be 12 complete sets of images.
A brief history of using bitmap fonts
The earliest user interface terminals such as teletype terminals used dot matrix printer mechanisms to print on rolls of paper. With the development of Cathode Ray Tube terminals bitmap fonts were readily transferable to that technology as dots of luminescence turned on and off by a scanning electron gun.
Earliest bitmap fonts were of a fixed height and width with the bitmap acting as a kind of stamp or pattern to print characters on the output medium, paper or display tube, with a fixed line height and a fixed line width such as the 80 columns and 24 lines of the DEC VT-100 terminal.
With increasing processing power, a more sophisticated typographical approach became available with vector fonts used to improve displayed text quality and provide improved scaling while also reducing memory required to describe the character glyphs.
In addition, while a matrix of dots or pixels worked fairly well for languages such as English, written languages with complex glyph forms were poorly served by bitmap fonts.
Representation of bitmap fonts in source code
There are a number of bitmap font file formats which provide a way to represent a bitmap font in a device independent description. For an example see Wikipedia topic - Glyph Bitmap Distribution Format
The Glyph Bitmap Distribution Format (BDF) by Adobe is a file format for storing bitmap fonts. The content takes the form of a text file intended to be human- and computer-readable. BDF is typically used in Unix X Window environments. It has largely been replaced by the PCF font format which is somewhat more efficient, and by scalable fonts such as OpenType and TrueType fonts.
Other bitmap standards such as XBM, Wikipedia topic - X BitMap, or XPM, Wikipedia topic - X PixMap, are source code components that describe bitmaps however many of these are not meant for bitmap fonts specifically but rather other graphical images such as icons, cursors, etc.
As bitmap fonts are an older format many times bitmap fonts are wrapped within another font standard such as TrueType in order to be compatible with the standard font subsystems of modern operating systems such as Linux and Windows.
However embedded systems that are running on the bare metal or using an RTOS will normally need the raw bitmap character image data in the form similar to the XBM format. See Encyclopedia of Graphics File Formats which has this example:
Following is an example of a 16x16 bitmap stored using both its X10 and X11 variations. Note that each array contains exactly the same data, but is stored using different data word types:

I want to request user input via PromptForChoice and then, based on what they select, do a certain action.
In my code I have three options: Laptop, Tablet, and Workstation . If the user selects one, I want to do a certain action as opposed to the other actions assigned to the other options.
In the code, I do not really understand the line containing the decision variable, or what the number 1 means either after $choices. I have put asterisks around the parts of the code I don't understand.
I do not know how to assign certain actions to one button. The first part of code is what I want to do but isn't working, and the last part is the actual script.

anywhere in the File Name
input field, then I get some very weird behavior. Namely, the user-entered text in the File Name
field gets copied to the Files of Type
field.

Answered 2021-Jun-08 at 01:06This if the FileChooser doing dynamic filtering on the file list.
If the user enters "?" then it will filter all file names with a single character.
if the user enters something like: "table*" it will filter all the files that start with "table".
if the user enters something like: "table?" it will filter all the files the start with "table" plus any other character.
In the BasicFileChooserUI
class the the FileFilter keeps getting reset with the GlobFilter
when either of the "*" or "?" characters is found in the file name.
I don't know how to disable this feature.
QUESTION
below I have posted the code for my drop-down menu. At the very end, there is a variable called variableToChange=""
.
Probably it is an easy question for the more experienced ones but I want every time I press some button to change the value of the variable. Let's say it should take the text of the button as a new value.
I guess it should be implemented somewhere into the on click
part but I lack the experience here so I can't really implement it. I would really appreciate some help.
Update: Expected scenario would be: when I press the button called AA the value of variableToChange should be changed to "AA". Similarly, if I press afterwards BC it should be changed again to "BC".

Install asterisk
PHP requires the Visual C runtime (CRT). The Microsoft Visual C++ Redistributable for Visual Studio 2019 is suitable for all these PHP versions, see visualstudio.microsoft.com. You MUST download the x86 CRT for PHP x86 builds and the x64 CRT for PHP x64 builds. The CRT installer supports the /quiet and /norestart command-line switches, so you can also script it.
