使用QtGui 添加icon
- .setIcon(QtGui.QIcon(':fileOpen.png'))
- 使用 .setIcon
- （':'）这里的 ：（冒号） 是Qt语法 表示是一个资源
def create_widgets(self):
self.select_file_path_btn = QtWidgets.QPushButton()
self.select_file_path_btn.setIcon(QtGui.QIcon(':fileOpen.png'))
使用 .setToolTip() 快速添加文字说明
- .setTipTool('Select File')
self.select_file_path_btn.setToolTip('Select File')
image.png
使用 cmds.resourceManager(nameFilter = '*png') 遍历 所有png的图标
import maya.cmds as cmds
for item in cmds.resourceManager(nameFilter = '*png'):
print item
image.png
check_box 可见性与 radio_btn 关联
force_check_box 可见性被 open_radio 关联时可见， 被其他 reference_radio, import_radio 点击时不可见
- update_force_visibility()槽函数传入 checked
- 当open_radio.toggled 到 update_force_visibility 为真时
- force_check_box.setVisible(checked= True)
def create_connections(self):
self.open_radio.toggled.connect(self.update_force_visibility)
def update_force_visibility(self, checked):
self.force_check_box.setVisible(checked)
文件图标添加Maya文件过滤器
file_path, selected_filter = QtWidgets.QFileDialog.getOpenFileName(self, 'Select File')
- file_path 文件路径
-
selected_filter 过滤的的文件格式
image.png
QtWidgets.QFileDialog.getOpenFileName(self, 'Select File')
- 得到 完整文件路径名
-
设置给 line_edit 路径文本信息
image.png
def show_file_select_dialog(self):
'''
:return:
'''
file_path, selected_filter = QtWidgets.QFileDialog.getOpenFileName(self, 'Select File')
if file_path:
self.file_path_line_edit.setText(file_path)
用类变量设置过滤文件格式
- 过滤格式放在字符串里
- 每两个之间用；；（两个分号）隔开
-
过滤器设置的格式下面
image.png
class TestUIWindow(QtWidgets.QDialog):
FILE_FILTERS = 'Maya(*.ma *mb);;Maya ASCII(*.ma);;Maya Binary(*.mb);;All Files(*.*)'
selected_filter = 'Maya(*.ma *.mb)'
- 填入 过滤 类变量
def show_file_select_dialog(self):
'''
:return:
'''
file_path, selected_filter = QtWidgets.QFileDialog.getOpenFileName(self, 'Select File',
'',
self.FILE_FILTERS,
self.selected_filter)
if file_path:
self.file_path_line_edit.setText(file_path)
Apply_btn 关联 load_file 槽函数
- load_file 槽函数 根据按钮去 调用
- open_file
- import_file
- reference_file
# load_file
- file_path 得到line_edit 的文件路径文本
- 判断文本有没有
- 判断是不是文件信息
- 判断radio_btn 被选择中的那一个去执行对应的条件下的函数
def load_file(self):
'''
:return:
'''
file_path = self.file_path_line_edit.text()
if not file_path:
return
file_info = QtCore.QFileInfo(file_path)
if not file_info.exists():
om.MGlobal.displayError('File does not exsit: {0}'.format(file_path))
return
if self.open_radio.isChecked():
self.open_file(file_path)
elif self.import_radio.isChecked():
self.import_file(file_path)
else:
self.reference_file(file_path)
Open_file 函数
- force 复选框没有选择并且文件被修改了，弹出信息。
- 如果信息是Yes，设置 打开文件 force = True
def open_file(self, file_path):
force = self.force_check_box.isChecked()
if not force and cmds.file(q = True, modified = True):
result = QtWidgets.QMessageBox.question(self, "Modified", "Current scene has unsaved changes. Continue?")
if result == QtWidgets.QMessageBox.StandardButton.Yes:
force = True
else:
return
cmds.file(file_path, open = True, iv = True, force = force)
使用类方法调用窗口
- 申明一个 dialog_instance = None
- 在类方法中判读这个类变量
- 实例化 TestUIWindow
- 判读这个隐藏就show
- 如果在前面就 激活 窗口
class TestUIWindow(QtWidgets.QDialog):
FILE_FILTERS = 'Maya(*.ma *mb);;Maya ASCII(*.ma);;Maya Binary(*.mb);;All Files(*.*)'
selected_filter = 'Maya(*.ma *.mb)'
dialog_instance = None
@classmethod
def show_dialog(cls):
'''
:return:
'''
if not cls.dialog_instance:
cls.dialog_instance = TestUIWindow()
if cls.dialog_instance.isHidden():
cls.dialog_instance.show()
else:
cls.dialog_instance.raise_()
cls.dialog_instance.activateWindow()
