# Button Highlighting Update
|
||
|
|
|
||
|
|
## ✅ Active Button Highlighting Implemented
|
||
|
|
|
||
|
|
Added proper visual feedback to show which frame type filter is currently selected.
|
||
|
|
|
||
|
|
## 🎨 Visual Appearance
|
||
|
|
|
||
|
|
### **Active Button (Selected)**
|
||
|
|
- **Background**: Blue (#0080ff) - same as the original tab highlighting
|
||
|
|
- **Text**: Bold white text
|
||
|
|
- **Class**: `-active` CSS class applied
|
||
|
|
|
||
|
|
### **Inactive Buttons**
|
||
|
|
- **Background**: Dark gray (#262626)
|
||
|
|
- **Text**: Gray text (#999999)
|
||
|
|
- **Hover**: Lighter blue background on mouse over
|
||
|
|
|
||
|
|
### **Button Layout**
|
||
|
|
```
|
||
|
|
[1. Overview] [2. CH10-Data(1105)] [3. UDP(443)] [4. PTP-Signaling(240)]
|
||
|
|
↑ Active ↑ Inactive ↑ Inactive ↑ Inactive
|
||
|
|
```
|
||
|
|
|
||
|
|
## 🔧 Implementation Details
|
||
|
|
|
||
|
|
### **Highlighting Logic**
|
||
|
|
1. **Initial State**: Overview button starts highlighted (blue background)
|
||
|
|
2. **Button Click**: Clicked button becomes active, others become inactive
|
||
|
|
3. **Keyboard Navigation**: Number key selection updates highlighting
|
||
|
|
4. **Dynamic Updates**: Highlighting preserved when buttons are refreshed
|
||
|
|
|
||
|
|
### **Key Methods Added**
|
||
|
|
- `_update_button_highlighting()` - Updates active/inactive state for all buttons
|
||
|
|
- Called after button selection, frame type refresh, and initial mount
|
||
|
|
- Uses CSS `-active` class for consistent styling
|
||
|
|
|
||
|
|
### **CSS Classes**
|
||
|
|
```css
|
||
|
|
#filter-bar Button.-active {
|
||
|
|
background: #0080ff;
|
||
|
|
text-style: bold;
|
||
|
|
}
|
||
|
|
|
||
|
|
#filter-bar Button {
|
||
|
|
background: transparent;
|
||
|
|
color: #999999;
|
||
|
|
}
|
||
|
|
|
||
|
|
#filter-bar Button:hover {
|
||
|
|
background: #0080ff;
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
## ⌨️ User Experience
|
||
|
|
|
||
|
|
### **Visual Feedback**
|
||
|
|
- **Clear indication** of which filter is currently active
|
||
|
|
- **Consistent styling** with the rest of the StreamLens interface
|
||
|
|
- **Immediate feedback** when switching between filters
|
||
|
|
|
||
|
|
### **Interaction Flow**
|
||
|
|
1. **Start**: Overview button highlighted in blue
|
||
|
|
2. **Press `2`**: CH10-Data button becomes blue, Overview becomes gray
|
||
|
|
3. **Press `3`**: UDP button becomes blue, CH10-Data becomes gray
|
||
|
|
4. **etc.**
|
||
|
|
|
||
|
|
### **Expected Behavior**
|
||
|
|
- Active button is clearly highlighted in blue with bold text
|
||
|
|
- Only one button highlighted at a time
|
||
|
|
- Highlighting updates immediately on selection
|
||
|
|
- Consistent with original tab-style highlighting you mentioned
|
||
|
|
|
||
|
|
## 🎯 Result
|
||
|
|
|
||
|
|
The button bar now provides clear visual feedback showing which frame type filter is currently selected, matching the highlighting style you referenced from the original tab interface.
|
||
|
|
|
||
|
|
The interface should now feel complete with proper active button indication!
