# Screenshot OCR Gallery
|
||||
|
||||
A Qt6-based image gallery application that allows you to search through OCR data from your screenshots with live preview.
|
||||
A Qt6-based image gallery application that allows you to search through OCR data from your screenshots with live preview and dynamic resizing.
|
||||
|
||||
## Features
|
||||
|
||||
- Fast visual navigation through your screenshot collection
|
||||
- Live search through OCR text as you type
|
||||
- 4×4 image gallery grid with 256px wide previews
|
||||
- Ultra-responsive live search through OCR text as you type with optimized performance
|
||||
- Dynamic grid layout that automatically reflows (1x, 2x, 3x, 4x, etc.) based on window width
|
||||
- No horizontal scrollbars - content always fits the window width
|
||||
- Filename overlay at the bottom of each image for easy identification
|
||||
- Opens images in your default image viewer on click
|
||||
- Responsive design that adjusts to window size
|
||||
- Minimal 2px spacing between images for a compact view
|
||||
- Proper error handling for missing files and database issues
|
||||
|
||||
## Requirements

@@ -88,9 +90,15 @@ After building, run the application:
|
||||
|
||||
1. When the application starts, it will display all screenshots found in the database
|
||||
2. Type in the search bar to filter images by OCR text content
|
||||
3. Results update as you type
|
||||
4. Click on any image to open it in your default image viewer
|
||||
5. Hover over an image to see the file path and a preview of its OCR text
|
||||
3. Results update instantly as you type with optimized search performance
|
||||
4. When you clear the search bar, all images are immediately shown
|
||||
5. Resize the application window to see the grid automatically reflow:
|
||||
- Wider windows show more columns (4x, 5x, etc.)
|
||||
- Narrower windows reduce to fewer columns (3x, 2x)
|
||||
- Very narrow windows show a single centered column (1x)
|
||||
- No horizontal scrolling - content always fits the available width
|
||||
6. Each image displays its filename at the bottom for easy identification
|
||||
7. Click on any image to open it in your default image viewer
