Qlineedit Text Color

// Set text color when the widget is inactive (window not in focus) palette.setColor(QPalette::Inactive, QPalette::Text, QColor(0, 0, 200));

// Set text color when the widget is disabled palette.setColor(QPalette::Disabled, QPalette::Text, QColor(150, 150, 150));

To set a specific color for the placeholder text independently (if your Qt version supports it), you generally have to do it programmatically or rely on the palette definition, as QSS support for ::placeholder pseudo-elements is limited compared to standard CSS. When the user highlights text, the default selection colors might clash with your new text color. You can control this via QSS as well: qlineedit text color

QPalette palette = lineEdit->palette(); // Set text color when the widget is active palette.setColor(QPalette::Active, QPalette::Text, QColor(0, 0, 255));

// 1. Get the current palette (so we don't lose other settings like background color) QPalette palette = lineEdit->palette(); // Set text color when the widget is

However, if you want to style the text inside the line edit but not the placeholder, you might rely on QPalette for the placeholder and QSS for the text, but generally, QSS applies to the main text rendering.

// 3. Apply the modified palette back to the widget lineEdit->setPalette(palette); One limitation of the simple approach above is that it can inadvertently affect other states. For example, if the widget is disabled, you might want the text to be a lighter gray, not your custom active color. Get the current palette (so we don't lose

To handle this correctly, you should set the color for specific groups:
